The famous mallat decomposition algorithm is applied . the correlations between the neighboring wavelet transform coefficients are utilized to restrain noises and the local maxima of the coefficients provide information of image boundaries 并利用相邻尺度间小波系数的相关性和一种非线性函数进行噪声抑制,同时利用小波系数的模极大值来提取边缘点。
Simulation result shows our approach can highly improve the connectivity and the accuracy of the image boundaries quickly and easily . ideally , the methods discussed in the previous section should yield pixels lying only on edges . edge connection is an important post - process technique of image edge extraction and image segmentation 完成边缘点的检测后,为了得到能够表现物体基元的边缘链,我们需要进行边缘连接的工作? ?将边缘点连接成有意义的直线或曲线段,得到物体外部的闭合轮廓,进行图像分割。
Based on fuzzy logic , an effective algorithm of edge connection is proposed . simulation result shows our approach can highly improve the connectivity of the extracted image boundaries without distortion . this work lays foundations of target detection , tracking , and recognition for photoelectric tracker and imaging radar 通过理论分析及仿真结果证明,本文提出的梯度参数自学习统计的方法和基于模糊判决的边缘连接方法能够有效地提取边缘点进行边缘连接,能够在保持原有图像不失真的情况下,较大地提高图像边界的连通性,为光电跟踪器和成像雷达的目标检测、跟踪和识别等提供良好的基础。
