Tips and tricks: recursive show images

The "Mastering OpenCV with Practical Computer Vision Projects" book is done and published!

Also : including a screenshot of each project ....

This will be the main issue .

... to see the screenshot from each project

...and also to find a way for any file to use

Let's take te book and source code:

$ git clone git://github.com/MasteringOpenCV/code.git

Go to the main folder : $ cd code and use this:

code]$ ls 
Chapter1_AndroidCartoonifier     Chapter7_HeadPoseEstimation
Chapter2_iPhoneAR                Chapter8_FaceRecognition
Chapter3_MarkerlessAR            Chapter9_FluidInteractionUsingKinect
Chapter4_StructureFromMotion     LICENSE.txt
Chapter5_NumberPlateRecognition  README.md
Chapter6_NonRigidFaceTracking

If we use the tree linux command the result will be:

.
|-- Chapter1_AndroidCartoonifier
|   |-- Cartoonifier_Android
|   |   |-- AndroidManifest.xml
|   |   |-- jni
|   |   |   |-- Android.mk

|   |   |-- cartoon.h
|   |   `-- main_desktop.cpp
|   |-- README.txt
|   `-- screenshot.png
|-- Chapter2_iPhoneAR

We need something to find the absolute path and give that to gthumb to run it.

First find the screenshot:

 code]$ ls -d  $PWD/**/*.png
/home/free-tutorials/code/Chapter1_AndroidCartoonifier/screenshot.png
/home/free-tutorials/code/Chapter2_iPhoneAR/screenshot.png
/home/free-tutorials/code/Chapter3_MarkerlessAR/screenshot.png
/home/free-tutorials/code/Chapter4_StructureFromMotion/screenshot.png
/home/free-tutorials/code/Chapter5_NumberPlateRecognition/screenshot.png
/home/free-tutorials/code/Chapter6_NonRigidFaceTracking/screenshot.png
/home/free-tutorials/code/Chapter7_HeadPoseEstimation/screenshot.png
/home/free-tutorials/code/Chapter8_FaceRecognition/screenshot.png
/home/free-tutorials/code/Chapter9_FluidInteractionUsingKinect/screenshot.png

Now will run gthumb with all this images:

code]$ ls -d  $PWD/**/*.png | xargs gthumb

Linus Torvalds - kernel 3.7 is now out.

From: Linus Torvalds <torvalds <at> linux-foundation.org>

Subject: Linux 3.7

Newsgroups: gmane.linux.kernel

Date: 2012-12-11 03:59:50 GMT (9 hours and 45 minutes ago)

Whee. After an extra rc release, 3.7 is now out. After a few more trials at fixing things, in the end we ended up reverting the kswapd changes that caused problems. And with the extra rc, I had decided to risk doing the buffer.c cleanups that would otherwise have just been marked for stable during the next merge window, and had enough time to fix a few problems that people found there too. There's also a fix for a SCSI driver bug that was exposed by the last-minute workqueue fixes in rc8. Other than that, there's a few networking fixes, and some trivial fixes for sparc and MIPS. Anyway, it's been a somewhat drawn out release despite the 3.7 merge window having otherwise appeared pretty straightforward, and none of the rc's were all that big either. But we're done, and this means that the merge window will close on Christmas eve. Or rather, I'll probably close it a couple of days early. For obvious reasons. It's the main commercial holiday of the year, after all. So aim for winter solstice, and no later. Deal? And even then, I might be deep into the glögg. Linus

Simple convert images using ImageMagick - convert features

Can be done by using ImageMagick.This is a software suite to create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats over 100. Using ImageMagick let you to resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.

Install the software under Fedora:

# yum install  ImageMagick 

Convert an image from one format to another. In this case jpeg.

$ convert *.png *.jpg
$ mogrify -format png *.jpg

Unusual commands in linux : pv

Today I will speak about pv command.

Pipe viewer - pv is a terminal-based tool for monitoring the progress of data through a pipeline written by Andrew Wood

To install pv on Fedora or CentOS do this:

$ sudo yum install pv

You can read the man file to get more help:

man pv

The result is:

NAME
       pv - monitor the progress of data through a pipe

SYNOPSIS
       pv [OPTION] [FILE]...
       pv [-h|-V]

DESCRIPTION
       pv  allows  a  user  to see the progress of data through a pipeline, by
       giving information such as time  elapsed,  percentage  completed  (with
       progress  bar),  current  throughput  rate, total data transferred, and
       ETA.

       To use it, insert it in a pipeline  between  two  processes,  with  the
       appropriate  options.  Its standard input will be passed through to its
       standard output and progress will be shown on standard error.

Let's see some examples.

You can get precisely time how long it will take.

$ pv voronoi.py | python 
 737B 0:00:00 [86.9kB/s] [==================================>] 100%

You can see how fast the computer reads from /dev/zero.

$ pv /dev/zero > /dev/null
1.1GB 0:00:05 [   2GB/s] [    <=>                                            ]

You can use the dialog to show progressbar.

To do this you need to use -n arg.

$ (pv -n /dev/zero > /dev/null) 2>&1 | dialog --gauge "Please wait" 10 70 0

Make one simple kernel module using C programming language.

Today I will try to explain how to make a kernel module.

Basically, a kernel module it's one pieces of code that can be loaded and unloaded into the kernel.

You can read about kernel modules from here.

Now, let's try to make a simple kernel module.

Writing your own module can be done if you know some basic rules.

First, about how to use modules.

Suppose you have a new module named kernelmoduletest.

How to load the module.

Just use this command in your module kernel folder:

#insmod kernelmoduletest.ko

Next, test the kernel module messages.

This can be done with:

#dmesg | tail

Also , you need to remove the kernel module.

$ rmmod kernelmoduletest 
ERROR: Removing 'kernelmoduletest': Operation not permitted

This mean you need to have superuser rights.So use the sudo or su command.

Then use the rmmod command.

Know how to make the kernel module skeleton.

This is not very simple because you need to know many things about kernel and programming.

But you can try test with some simple example like this example:

Create the c file named kernelmoduletest and add this source code:

#include <linux/module.h>
#include <linux/kernel.h>

MODULE_LICENSE("GPL");
MODULE_DESCRIPTION("kernelmoduletest");
MODULE_AUTHOR("Catalin George Festila/mythcat/catafest");

int init_module() {

    printk(KERN_INFO "Now I will initialize my  kernel module\n");

    printk(KERN_INFO "Test: Hello World !\n");

    return 0;
}

void cleanup_module() {

    printk(KERN_INFO "Bad!... kernel module unloaded.\n");
}

Make a new file named Makefile.

Add this to tell how to compile the kernel module.

obj-m += kernelmoduletest.o
all:
 make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
clean:
 make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean

Compile your kernel module

Just use make command.

# make
...
  Building modules, stage 2.
  MODPOST 1 modules
...
make[1]: Leaving directory `/usr/src/linux-headers-2.6.31-14-generic'

If you test your module using the commands from the top of this tutorial, you can see that:


[14694.779227] Now I will initialize my  kernel module
[14694.779233] Test: Hello World !
[15049.825605] Bad!... kernel module unloaded.

If you have already made kernel modules and the subject it's interested for you, send me an email.

Thank you. Regards.

Tips and tricks: watch and cat

Sometimes it is necessary to find solutions.

Today's example involves two linux commands:

watch and cat

Here is a simple method by creating a script that returns an output:

while [ 1 ]; do cat /proc/meminfo; date; echo; sleep 1; done

Make this script executable and name it: meminfo

Output is then processed by the command:

$ watch -d ./meminfo 

This simple method can be applied to other files ...

Using SL4A bash shell script to connect Linux with Android tablet .

Using Linux with Android OS is very simple.

I install next two android application: sl4a_r6.apk and PythonForAndroid-r7b1.apk.

Use the PythonForAndroid-r7b1.apk just if you want to write some python scripts.

We cand download it from here.

The first : sl4a_r6 it's use to write and run scripts like bash shell , html , java , python ...

With this, the SL4A provides and make APIs available via JSON RPC calls.

The PythonForAndroid-r7b1 allow you to install python modules...

We can read more on this website.

Let's start with one simple bash shell script.

We will make a shell script to test the connection between Linux and Android tablet.

Connection will be through a wireless router that has opened the port through which the communication.

Tablet has Android 4.0 .

We use the linux command nc, see: nc command.

This is the script on the tablet and it will run first.

nc -l -p 7000

See the next image:

Button 1 - run the script

Button 2 - edit the script

Button 3 - save the script

Button 4 - remove the script

Use the next command with your IP on the linux terminal.

nc xxx.xxx.xxx.xxx 7000

If you type something in your terminal you will see on tablet.

The input from my linux terminal can be see on the next image:

Ant this is the output on my tablet.

We can test multiple features of command nc. I'm just curious if you have some new ideas on this subject.

Thank you.

Testing your disks using dd utility and time.

You can execute copies a large block of data to and from disk.

This will minimize disk caching.

Next is one example if our test system has 1GB of RAM.

It is easy ( 1GB = 250,000 blocks ).

$ time sh -c "dd if=/dev/zero of=bigfile bs=8k count=250000 && sync"
250000+0 records in
250000+0 records out
2048000000 bytes (2.0 GB) copied, 37.0113 s, 55.3 MB/s

real 0m40.910s
user 0m0.172s
sys 0m12.641s

It's very hard to argue with this dd test.

Using DIGITAL PEN CAMERA eheV1-USB-II with mplayer

It's not my camera , I take it just to try to make working on Linux OS.

This is the device.

The dmesg tell me about this camera:

If you want to see and not to take frames, than use :

mplayer tv:// driver=v4l2:width=640:height=480:device=/dev/video0 -vo null

You can try to take some frames. I use this:

mplayer tv:// -frames 10 -tv fps=20:driver=v4l2:width=640:height=480:device=/dev/video0 -vo jpeg

The result is ten frames.

On this image I draw one line to see how working default.

Show large image like thumbnails in firefox using greasemonkey

Today I focused on a problem you often encounter.

We have a web folder containing a series of large image files. We want to see the folder that contains but would be difficult to download all the images and then view them search to find a picture of us.

I installed Greasemonkey addon and I began to study how it works.

I don't have experience with javascript programming.

I still managed to make the script below:

// ==UserScript==
// @name        show-image
// @namespace   show-image
// @description show images from files
// @include     http://*
// @version     0.1
// ==/UserScript==
var elements = document.getElementsByTagName("a");
  for (var i=0; (anchor=elements[i]); i++) {
   src = anchor.getAttribute("href");
  if (src.indexOf('.gif') > -1 || src.indexOf('.jpg') > -1 || src.indexOf('.JPG') > -1 || src.indexOf('.jpeg') > -1)
  {
    img = document.createElement('img');
    img.setAttribute('src',src);
    img.style.width='10%';
    anchor.appendChild(img);
   }
  }

You can add to show the png file by adding in the if condition in the script :

src.indexOf('.png') > -1 || src.indexOf('.PNG') > -1

I hope to help you.

Fedora online defragmenter for ext4 filesystem

The tool is e4defrag.

The man page tell us: reduces fragmentation of extent based file. The file targeted by e4defrag is created on ext4 filesystem made with "-O extent" option (see mke2fs(8)). The targeted file gets more contiguous blocks and improves the file access speed.

Let's try this tool.

You can try under root account this:

# e4defrag -test -cv /home/your_user/

The final result on my account is :

Total/best extents 170276/165520 Fragmentation ratio 0.03% Fragmentation score 0.24 [0-30 no problem: 31-55 a little bit fragmented: 55- needs defrag]

Also you have to run e4defrag with the -test parameter for now, since it isn't a fully tested version.

The new Blender 3D version 2.62 working well with Nouveau

Blender 3D version 2.62 works well with Fedora 16 drivers Nouveau. Here's a screenshot:
It should be noted the team effort which significantly improved the software. I would say that is a professional software. We can see the video review make by blendercookie with this new features. Video card is FX 5500 and working well with Nouveau. Blender 3D rendered very well and response console was it:

Overview of Blender 2.62 working with nouveau driver without 3d features

I would like to present one of the best presentations for Blender 2.62. This is a video on youtube, one of the best video presentations in English language, I would have preferred a Romanian subtitles, if they are willing to contact me. What is presented in this video reflect well the new features Blender 3d. Another important aspect esteca if you use linux with nouveau driver on Linux, it will work without 3d support, so as to allow the driver. I test this version with Fedora and nouveau driver and working well without 3d features of nouveau driver. This help much the users.
