need the best algorithm for shape features extraction with complex shaoe
显示 更早的评论
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?

I did answer. See above. Basically I don't know how to detect an infinite variety of bombs or whatever under the very complicated underside of vehicles which varies tremendously from one vehicle to another. Since you took on the project I presume that you have some plan or algorithm in mind. I certainly don't have anything that I can do for you in my 5 minute time limit. You're not going to do it in 5 minutes are you? I can't either. You're probably working on it for your Ph.D. so it's way too complicated for me to do for you in 5 minutes.

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.
