Structure of Dual-tree Complex Wavelet Filter on B-spline in Image Edge Detection

摘要：

This electronic Aiming at the Characteristics of image edge detection based on dual-tree complex wavelet transform, an algorithm is put forward to in the paper, which is used to structure a dual-tree complex wavelet filter based on B-spline wavelet There are both the benefits of shiftinvariance, good directional selectivity in dual-tree complex wavelet and optimal gradualness in B-spline wavelet Experiment results show that, compared with the Canny, discrete wavelet transform, dual-tree complex wavelet transform, the algorithm in the paper is more efficient with both precise image detection and effective noise restraining.
