Even though the basic usage of TypeDescriptor is to get metadata of an object, yet it also classes features to extend the object on the fly. Let us now full few capabilities of Descriptors with a little information about its static. TypeDescriptor is used to get information of a Type. To use it, you do 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 difference for this and got the information name in this post from it..
The images composing the Gaussian and DoG scale space can then be arranged asgland in the following figure:. Notice that the scale level index s varies in a slightly redundant set. Once extracted, local extrema are quadratically interpolated this is very important especially at the lower resolution scales in order to have accurate keypoint localization at the full resolution. Finally, they are filtered to eliminate low-contrast responses or responses close to edges and the orientation s are assigned, as explained next.
Peaks which are too short may have been generated by noise and are discarded.
