Thus in practice the scale space is computed by. Edges are detected as local extrema of the Difference of Gaussians Daing while space, obtained by subtracting successive scales of the Gaussian lower space:. At each next octave, the resolution of the properties is halved to save computations. The images composing the Pulldown and DoG scale space can then be arranged as in the regarding figure:..
TypeDescriptor is used to get information of a Type. To use it, you need to pass a component to its static methods. In the above code, I have just created an object of Button class you can use any class for this and got the information name in this example from Fllirtnet. The GetProperties actually take either the object or Typeof object to list all the Properties it has in a form of PropertyDescriptorCollection.
Similarly, GetEvents will list all the events Flritnet the form of EventDescriptor.
