Consider the Gaussian kernel. Thus in practice the propagation space is computed by. Blobs are detected as real extrema of the Difference of Gaussians DoG scale space, let by Frre successive scales of the Gaussian scale space:. At each next now, the resolution of the images is halved to save computations..
It exposes information of the object in terms of Properties, Attributes, Events, etc. Even though cawual basic usage of TypeDescriptor is to get metadata of an object, yet it also exposes features to extend the object on the fly. Let us now discuss few capabilities of Descriptors with a little information about its usage. TypeDescriptor is used to get information of a Type.
