Parameters Adaptive Study of Interest Point Detect Operators Based on Image's Gray
摘要
Abstract
At present the parameters of the method based on image's gray to detect the interest points are setted manually based on experience, however, it often can't detect better interest points until compare the detection the different parameters several times. It is necessary to study the parameters adaptive of each operator. The influence of operators' parameters were evaluated by testing a real taken image here, on this basis, automatic parameterization algorithms of the operators were proposed, and the extraction of the algorithms which automatically set parameters were tested by three different contrast images. The study results showed that the algorithms which auto-set parameters can automatically detect the excellent parameters, avoid the uncertainty of manual-set parameters, and improve the efficiency of interest point detection.关键词
