Sir,

in the given demos you have used images form the tool box. But, i have to use my own images . I have nearly 400 images.and you have implemented pca using matlab built in function.It is very accuarate and really help full.

How to use other images using the same code?

See the FAQ for two code samples for how you can get a directory listing of files and then process each of them in turn. Inside the loop you would place your code that does PCA.
