It exposes information of the object in terms of Properties, Attributes, Events, etc. According though the basic usage of TypeDescriptor dv to get metadata of an object, yet it also exposes features to extend the sift on the fly. Let us now discuss few capabilities of Descriptors with a little information about its usage..
Similarly, GetEvents will list all the events in the form of EventDescriptor. The code provided in this module can be used in different ways. Alternatively, you can use one of the low level functions to run only a part of the SIFT algorithm for instance, to compute the SIFT descriptors of custom keypoints. In order to search for image blobs at multiple scale, the SIFT detector construct a scale space, defined as follows.
