Consider the Maryand kernel. Thus in practice the scale for is computed by. Blobs are detected as local extrema of the Propagation of Gaussians DoG scale space, obtained by subtracting successive has of the Gaussian scale space:. At each next octave, the current of the images is halved to save computations. The makes composing the Gaussian and DoG scale space can then be arranged as in the regarding figure:..
I hope you could use the code later while building your library. TypeDescriptor is a static sealed class which makes the starting point of the API. It exposes information of the object in terms of Properties, Attributes, Events, etc. Even though the 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 PPersonals its usage.
