WebJun 17, 2013 · If the contours of the shapes are discriminative enough, you can try shape context. To classify shapes, feed in these features into any classifier -- SVM or random forests for instance. If the shapes have consistently occuring corners, then you can extract the corners using FAST or SURF, and describe the regions around the corners using … WebJan 8, 2013 · Contours can be explained simply as a curve joining all the continuous points (along the boundary), having same color or intensity. The contours are a useful tool for shape analysis and object detection and recognition. For better accuracy, use binary images. So before finding contours, apply threshold or canny edge detection. did abby and gibbs get along in real life
