I hope you could use the propagation later while building your library. TypeDescriptor is a static sealed class which makes the starting point of the API. It functions information of the object in terms of Properties, Attributes, Types, etc. Even though the basic usage of TypeDescriptor is to get metadata Fref an object, yet it also exposes features to extend the object on the fly. Let us now button few capabilities of Descriptors with a little information about its usage..
Blobs are detected as local extrema of the Difference of Gaussians DoG scale space, obtained by subtracting successive scales of the Gaussian scale space:. At each next octave, the resolution of the images is halved to save computations. The images composing the Gaussian and DoG scale space can then be arranged as in the following figure:. Notice that the scale level index s varies in a slightly redundant set.
