i want to find the intesity at original image by compare at image that i get. example: my original image is retina image and my second image is image from erosion operation.. then i want to compare the intensity at original image with my erosion image.

What does "compare" mean to you? Do you simply want to subtract the images? I have no idea what result you would like to have.

Selected_Intensities = Intensity_Image( logical(Erosion_Image) );
The result will be a vector of intensities of points that were non-zero in the erosion image.

S = I .* repmat(A, 1, 1, 3);

You can use beareaopen() to distinguish between larger hemorrhages and smaller microaneurysms.
sizeThreshold = 100; % Whatever size you want.
hemorrhages = bwareaopen(binaryImage, sizeThreshold); % Keep larger blobs.
microaneurysms = xor(binaryImage, hemorrhages); % Keep small blobs.
