Kernel designs for efficient multiresolution edge detection and orientation estimation
R. Wilson, Abhir H. Bhalerao · IEEE Transactions on Pattern Analysis and Machine Intelligence · 1992
Deals with the design of filter kernels having specified radial and angular frequency responses based on combined optimization and frequency sampling. This is used to generate small-radius, low-pass, and edge-detection kernels for multiresolution pyramids. The performance of the new kernels in estimating orientation is shown to be significantly better than that of other commonly used pyramid kernels.>
