Hi

I am new to MATLAB and recently started studying MATLAB and it is quite intresting.
I need to find out some features of an image in my project using MATLAB such as dark noise, dead pixels and image centroid and optical centre.

I am learing how to use MATLAB but i dont know the algorithms to implement all these features in MATLAB.

Kindly tell where can I get the details of these features so that i can implement the same in MATLAB??


thanks and regards
mkapoor

Generally, it is considdered good custom to do your own homework. Secondly, it is considdered good custom to at least try to do your homework before asking someone else to do it for you.

However, as a good measure, I will show you how to find dead pixels:
deadPixelIndices = find( imageData(:) < deadPixelThreshold );

There are of course many other ways, but that is the simplest one.
