designing a fast locking pll
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
Fast Template Matching
Although it is well known that cross correlation can be efficiently implemented in the transform domain, the normalized form of cross correlation preferred for template matching applications does not have a simple frequency domain expression. Normalized cross correlation is usually computed in the spatial domain for this reason. This short paper shows that unnormalized cross correlation can be ...
متن کاملFAST: Fast Adaptive Silhouette Area based Template Matching
Template matching is a well-proven approach in the area of articulated object tracking. Matching accuracy and computation time of template matching are essential and yet often conflicting goals. In this paper, we present a novel, adaptive template matching approach based on the silhouette area of the articulated object. With our approach, the ratio between accuracy and speed simply is a modifia...

متن کاملFast Affine Template Matching over Galois Field
In this paper, we address the problem of template matching under affine transformations with general images. Our approach is to search an approximate affine transformation over a binary Galois field. The benefit is that we can avoid matching with huge amount of potential transformations, because they are discretely sampled. However, a Galois field of affine transformation can still be impractic...
