A Valley Operator for Extracting Sketch Features
스케치 특징의 추출을 위한 밸리 연산자
Abstract
A new valley operator is presented for extracting sketch features which contain valleys and edges subject to local intensities. It is a very simple operator using the local probablities in a 3x3 local window. Experimental results show its excellent performance over the existing valley or edge operators.
