An interesting Image Processing Research Group's home page
http://iprg.co.in/
A
group of people motivated to work in Image Processing Domain. IPRG is a
community of engineers and researchers who share an interest to join in
the evolution of image processing research domains. The objective of
IPRG is to provide details which helps in the research as well as
information sharing. This group is an open community and any interested
individual can join the group.

Setup C compiler in Matlab Environment
Running mbuild
- Run mbuild -setup from MATLAB.
Select a compiler. Additional platform-specific information follows.
Windows
Executing mbuild -setup on Windows displays a message of this type:
Welcome to mbuild -setup. This utility will help you set up a default compiler. For a list of supported compilers, see http://www.mathworks.com/support/compilers/R2012a/win64.html Please choose your compiler for building shared libraries or COM components: Would you like mbuild to locate installed compilers [y]/n? n Select a compiler: [1] Microsoft Software Development Kit (SDK) 7.1 [2] Microsoft Visual C++ 2005 SP1 [3] Microsoft Visual C++ 2008 SP1 [4] Microsoft Visual C++ 2010 [0] None
The preconfigured options files included with MATLAB for Windows appear in the following table.
Note These options apply only to the 32-bit version of MATLAB.
MESSIDOR: Digital Retinal Images
The MESSIDOR database has been established to facilitate studies on computer-assisted diagnoses of diabetic retinopathy. The research community is invited to test its algorithms on this database. On this page, you will find instructions on how to download the database.

Who is Lenna?
![[Standard Lena Image]](https://lh3.googleusercontent.com/blogger_img_proxy/AEn0k_uPKTsGW8yDoDr4TFb7TdcDFTVd1u_XvX7BYxaJewKVLA2A-0qqVCRnVX_0u_bCv6gQeUiGjT-nAeLgaZ_WlzQwvWMlNjtGYm7iXLfomJgLjOHROAeQ=s0-d)
Introduction
The Lenna (or Lena) picture is one of the most widely used standard test images used for compression algorithms. The comp.compression FAQ says the following:
Over the years there has been quite a bit of controversy over the use of this image. Some people proposed banning the use of this image because of its source. Also, Playboy threatened to prosecute the unauthorized use of the image. Check out an editorial by the editor of SPIE journal Optical Engineering. Check out a note by the former editor-in-chief of the IEEE Transactions on Image Processing. According to Wired Magazine, Playboy has eased up in its pursuit of the copyright violators of this image. |

Random Dithering
For each value in the image, simply generate a random number 1..256; if it is greater than the image value at that point, plot the point white, otherwise plot it black. That's it. This generates a picture with a lot of "white noise", which looks like TV picture "snow". Though the image produced is very inaccurate and noisy, it is free from "artifacts" which are phenomena produced by digital signal processing.
