A structuring element is a shape mask used in the basic morphological operations. They can be any shape and size that is digitally representable, and each has an origin. 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 …

WebA Riemannian framework is used to derive the shape analysis of the extracted patches. The applied framework permits to calculate a similarity (or dissimilarity) distances between patches, and to compute the optimal deformation between them. ... Computer vision.

In this work, we present a novel approach to face recognition which considers both shape and texture information to represent face images. The face area is first divided into small regions from which Local Binary Pattern (LBP) histograms are extracted and concatenated into a single, spatially enhanced feature histogram efficiently ...

This scheme is based on a skeleton matching algorithm (SMA) which renders the similarity between two MSTs as a distance measure.
WebFeb 1, 2016 · In computer vision and image processing, image moments are often used to characterize the shape of an object in an image. These moments capture basic statistical properties of the shape, including the area of the object, the centroid (i.e., the center (x, y) -coordinates of the object), orientation , along with other desirable properties.
