Distance Functions and their Uses. The distance function of an object is a very simple and useful concept in shape analysis. Essentially, each pixel in the object is numbered according to its distance from the background.
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 … WebNov 1, 1992 · In this paper a scheme is presented for binary shape recognition which uses the MST representation. This scheme is based on a skeleton matching algorithm (SMA) which renders the similarity between two MSTs as a distance measure.
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.
