Image Processing in Matlab

This video demonstrates (very briefly!) the image processing capabilities of Matlab. A full res version can be found at http://blanchard.ep.wisc.edu/ These videos were recorded for a course I teach as part of a distance masters degree. See http://mepp.engr.wisc.edu

sir would u plz help me with codes for 'image retrieval using fourier descriptor'........here i have a image database and a query image, then i need to compare the fourier descriptor of the query image to that of the fourier descriptors of the images in the database and thus retrieve the best possible matching image from the database......plz help sir

I'd be happy to help, but I don't have time to write something like this for you. If you send me something that you think should work, I can take a look at it.

Also, you might consider using the Image Processing Toolbox. It might make all this quite a bit easier.

hello sir, i have a project based on diabetic retinopathy where i have to eliminate the optic disc from the retinal image & find only the excudates. can you gve me the function or full code for this.

@sudeshna131

You would have to give me more information. I have no idea what an excudate is, for example.

I think the image processing tools in Matlab 7 were quite a bit different from current tools. You also need the image processing toolbox for all of this to work.

Thanks for sharing.

dct2 is part of the image processing toolbox. Perhaps you don't have that toolbox. If you have it and it still doesn't work, then maybe there is an issue with version 7 of Matlab. I don't have access to Matlab 7 to test this.

sir i got error when i run this m file.

i am using matlab 7

what can i do for it sir.

??? Attempt to execute SCRIPT dct2 as a function.

Error in ==> dct2 at 6

J=dct2(I);
