multiple ocurrence in image rotation invariant
Hi,
I have various template images and one big image with multiple ocurrence of each template in it, but are rotated.
I have tried with SIFT and SURF but only work with one ocurrence of each template and matchTemplate is not rotation invariant.
Please, could you give me any suggestions? Thanks.
Why SURF/SIFT don't work with more than one occurrence of each template? Can you upload the matching image?
I am a new user and the forum don't permit answering my own question before of two days. But I try explain the matching image.
The keypoints in the template are associated with some keypoints of the image, but the set of keypoints of template are spliting in all matching in the image and if the number of matching is high in some matching don't exist some association.
I have thought to use sliding roi of size of max(template.width, template.height) and apply SIFT/SURF and each iteration (similar to matchingTemplate but with SIFT/SURF), but it is very slow and probably don't work because the size of roi is ever the same.
Just to for the record: As a poster, you may edit your own question to add more info / image / code at any time. So you could edit it to show the results.
