New method for fast image edge detection based on subband decomposition
Chongyang Hao, Min Qi, U. Heute, C. Moraga
Izvirni znanstveni članek
Oznake:
A new method of detection the edges of an image is presented in this article. The method uses a kind of twodimensional subband spectrum analysis (2D-SSA) filter that is based on subband decomposition, and it is very convenient to get the edge frequency spectrum of an image after certain preprocessin ...

Adaptive skin detection under unconstrained lighting conditions using a bigaussian model and illumination estimation
Jian-Hua Zheng, Chongyang Hao, Yang-Yu Fan, Xian-Yong Zang
Izvirni znanstveni članek
Oznake:
An algorithm is proposed to improve the performance of skin detection algorithms under poor illumination conditions. A hybrid skin detection model is addressed to solve these problems by combining two Gaussian models of skin under normal conditions and bright illumination. According to the distribut ...
