i am currently doing a project on image processing using matlab.it will be helpful if some one can tell me a good algorithm to find out the correlation between 2 images.also i need to have an idea about embedding matlab code in simulink.please help if anybody knows about this Posted in: #Coffee Room

hey buddy you can use simulink in matlab by checking out its help topics... its really simple to make programmes using simulink...and we can also apply them in embedded system...

guys one query in matlab
suppose i am controlling a hardware object(say a micromouse) with a preloaded program on a microcontroller. now if i want to retrieve the signals from microcontroller that it is sending to my object, which toolbox i can use? is it DAQ? and where from i can get a good DAQ tutorial..

YA THATS RIGHT...you can use DAQ for retriving your signals through matlab...
Data Acquisition Toolbox enables you to customize your acquisitions, access the built-in features of hardware devices, and incorporate the analysis and visualization features of MATLAB and related toolboxes into your design. You can analyze or visualize your data, save it for post-processing, and make iterative updates to your test setup based on your analysis results. Data Acquisition Toolbox allows you to use MATLAB as a single, integrated environment to support the entire data acquisition, data analysis, and application development process.
Data Acquisition Toolbox also supports Simulink with blocks that enable you to incorporate live data or hardware configuration directly into Simulink models. You can then verify and validate your model against live, measured data as part of the system development process...

wow,
thanks for such an informative post buddy.
but my concern remains unanswered, i dont knw specifically how to use DAQ. i read the help given in matlab but not that much useful.

so i wanted to know a tutorial that helps me understanding DAQ

That depends on what, precisely, you mean by "correlation between 2 images". If the images a registered ("aligned"), then simple measures like mean absolute difference (in MATLAB: mean(A( : ) - B( : ), or the correlation coefficient (in MATLAB: corrcoef(A( : ),B( : )) for the complete correlation matrix) are obvious possibilities.

If the images are not registered, or you need to match some other characteristics of the images, then more information would be needed to answer your question.
