Hi, to find regions having the higher MeanIntesity compared to the MeanIntesity of its edge, I used this line but I got an error. thank you for helping me to find the right solution.
image=imhmin(I,4,8);
edg = edge(image,'log',0);
m1 = bwmorph(edg,'spur');
m2 = bwmorph(m1,'hbreak');
I2=imfill(m2,'holes');
holes = I2 & ~m2;
imagebin1 = bwlabel(holes,8);
imggris1=I;
imggris1 (imagebin1 ==0)=255;
imagebin2 = edge(imggris1,'log',0);
imggris2=I;
imggris2(imagebin2==0)=255;
ad = regionprops(imagebin1, imggris1, 'MeanIntensity');
det = regionprops(imagebin2, imggris2, 'MeanIntensity');
feim = find([ad.MeanIntensity]>[det.MeanIntensity]);
The error:
??? Error using ==> gt
Matrix dimensions must agree.
Error in ==> detect_fea at 41
feim = find([ad.MeanIntensity]>[det.MeanIntensity]);

[ad.MeanIntensity] and [det.MeanIntensity] at line 41 of detect_fea are not the same size. The operation [ad.MeanIntensity]>[det.MeanIntensity] requires that they both be the same size or one of them be a scalar.
Use the DSTOP command or breakpoints to pause your code at line 41 to examine what happened. Apparently, though, regionprops did not find the same number of regions in both ad and det.

For some reason you don't have as many blobs in ad as you do in det.

I wouldn't even do it like that. I'd use bwperim as a mask to get the outer layer of your blobs. I think with bwperim you should have the same number of blobs.
