Simulating human vision system.

Hi, I am involved in a project wherein i have to extract parts of a photograph corresponding to human eye movements , like when the human eye sees upwards what would be the portion which would have maximum intensity and so-on. I have been asked to do this project in matlab and have no experience whatsoever. any help would be appreciated.

I have to say that if you have no experience of MATLAB this is quite a tough project to start with. It's easier to learn a new language with a series of small, well-defined tasks, and so Jos (10584) certainly has a point. If you do go ahead, you need to swiftly get a firm grip on MATLAB, and some suggestions for this are here:

In addition, you should make sure you have access to the Image Processing Toolbox, and read its documentation and study its demonstrations carefully.

Looking further ahead, it is possible that the following FEX submission may be useful at some stage:

The reason is that the human eye, unlike most digital cameras, has a spatially-varying resolution. This is one of several aspects of vision that you may want to simulate. The resolution of the eye is sometimes approximately modelled by the log-polar distribution, and so in capturing the effect of eye movements you may wish to resample the image in this way - moving the sampling centre is a rough analogue to making eye movements.

thanks a lot for ur valuable comments.

There is no answer for this question (if it is a question at all ...). I can only give you this advice: go to the one who asked you to "do this project" and say "No" or, perhaps, "No, unless ...".
