摘要
本文研究了多灰度层次图象目标在复杂背境和噪声干扰下的多级检测技术。该检测器考虑了可视目标的灰度特性和空间特征以及错误检测的统计特性。对多级检测器作了理论上的分析和计算机模拟,并将研究的结果应用于X光片骨龄识别上,获得了较好的实验结果。
In this paper, a multi-threshold progressive detection (MTPD) method of visible image ob-jects in noisy complex background is studied. Visual properlies of gray contrast and spalial size and minimum error detection probability are ccnsilered. The theoretical model and the computer software imp-lementation of MTPD, as well as its application in X ray bone age recognition are presented. The practical test results show that the performance of MTPD is good.
