I\'m working with eigenfaces for a facial recognition program I am writing. I have a couple questions about how eigenfaces are actually generated:
i\'m using LSD to detect straight lines in an image, the code that i have downloaded contains a Minimal example of calling LSD but it\'s static (i.e it outputs only the value in the main function) i w
I have been using many implementation of SIFT. Some of the features when drawn extend over the edge of the image. They tend t开发者_StackOverflow社区o use a conversion of 6 * sigma to convert from sca
I\'m trying to get OpenCV to recognize开发者_如何学C a visual badge (marker). Does anyone have an existing HaarCascade (preferably an xml file) of a badge of some sort?
I\'m searching for a usable metric for SURF. Like how good one image matches another on a scale let\'s say 0 to 1, where 0 means no similarities and 1 means the same image.
I was wondering if anybody has a recommendation for an image format that supports integer-valued images in the range [0, 2^32] or higher, e.g. [0, 2^64]. I am interested in solutions that may already
I\'m suppressing the low DC frequencies of several (unequal) blocks in an image in the Dicrete Cosine Transform (DCT) domain. After that doing an inverse DCT to get back the image with only the high f
I have to implement a Harris detector and am not quite sure about the following detail regarding the Sobel filter to obtain the image derivative.
I see HOG is often used with SVM for target detection, can it be used in matching keypoints in tw开发者_开发技巧o images?
I\'m trying to write my own implementation of Watershed Segmentation for a project. I have a version that returns something resembling the correct segmentation given really trivial pictures. Unfortuna
