Hi every body ....if i have complex shape which i Interested in Details of shape..which algorithm can help me to extract the features of this image.... I found the (phog_algorithm)can this algorithm help me????pls help me
this is my image...
i want to extract the shape features of it to make it Ultimate from others cars..
the phog alograthms have this code
function [ features ] = phog( images, bins, L, mode )
features = [];
for group=1:length(images)
fprintf('Analyzing group %d...\n', group);
for image=1:length(images{group})
img = imresize(images{group}{image}, [400 400]);
f = anna_phog(img, bins, 180, L, [1 size(img,1), 1, size(img,2)]', mode);
features(image, :, group) = f;
end
end
end
plz help me

Never heard of it. Why don't you post your image and tell us what shapes you want to distinguish from each other? in the meantime, see this: http://en.wikipedia.org/wiki/Morphometrics It's always best to attach an image when asking for image processing advice.
[EDIT] I can't make out anything in that image. Just looks like a mess to me. Good luck though.

What features will do you any good? About all I know for the feature of an edge is the length of the edge. Do you want that?

hi image analyst...after i read about shape features i understood some thing..: to detections shape we need to detection the global and local features...but i get Thumbs in some algorithm to used..i get PCA && SIFT && hog..what the defferent between them? which image can extract the featuers when have have similarty images?? i hope my questions clear for you...plz help me

I don't recognize anything in that picture except a drive shaft and tires. And I don't have any code for segmenting out drive shafts or tires. Sorry.
