摘要：Contemporary Chinese aesthetics have three important ＂traces＂： ego aesthetics represented by Chinese fantasy literature; convoluted aesthetics represented by the contemporary Chinese movie ＂Loss＂ and the novel Monk; and the fetish aesthetics of symbolic exchange, as represented by Huang Xiaoming＇s wedding and the auctioning of Jack Ma＇s painting. These represent the transmutation of contemporary Chinese aesthetics from adolescent ego aesthetics to adult convoluted aesthetics to the fetish aesthetics of symbolic exchange, thus completing the successive change of logic from ego to society to reality. In tracing these successive changes in logic, we are thinking about questions raised by the times. These concern the future of Chinese contemporary aesthetics and constitute an aesthetic revolution. They mean that contemporary Chinese aesthetic practice has moved from text to community and then evolved into social reality. Further, they also smack of mutual imitation between aesthetics and life. Contemporary Chinese theorists should be actively involved in the revolution, responding to major issues and, as they face social practices, acquiring transcendental characteristics in contemporary aesthetic leadership.

摘要：The Canny edge detector inevitably misses some important and obvious edges during contour extraction, which causes gaps in the contour. A geometric method to locate, measure and fill the gaps precisely is proposed. With the complete contour information, a convolution approach is presented, which utilizes an appropriate linear interpolation to resample the contour to calculate pointwise curvature. This approach distributes discrete points within a convolution window uniformly. It ensures a one-to-one correspondence between every point and its weight, thus the accuracy is guaranteed under this condition. A related parameter selection is also suggested. Experimental results show that the proposed methods are robust and accurate.
