Kindly help me thanks.
Database = imageSet('Palm','recursive');
for i=1:size(training,2)
for j = 1:training(i).Count
image=read(Database(i),j);

Database((i),j)=image; %for replacing the same image

YOu have to save the image in a folder of your choice, using imwrite. And then in that folder use imageSet.

Database = imageSet('Palm','recursive');
for i=1:size(training,2)
Filenames = Database(i).Locations;
for j = 1:training(i).Count
image=read(Database(i),j);
image=imresize(image,0.568);
imwrite(image, Filenames{j}) ;
end
end
This code is not recommended. Every time you run it, it will shrink the files by the same factor. If there is a problem part way through such as a file permissions problem then you would need to move the files that had already been processed to a different directory or else they would get shrunken again.
It would be safer if you specified an output size instead of a scaling factor: then it would not matter how many times you ran the code on the same file.
