摘要
为了找到美元图像4个边缘的宽度,首先对图像进行长、宽方向的投影。投影信号中的突变最激烈的点就是边缘的起始处和终止处,将小波变换检测信号的奇异性理论应用于这种突变点的检测中。详细地分析了如何选择合适的小波基以及如何选择合适的尺度来进行突变点的定位方法。
In order to find the width of four homers in dollar image, projections were first performed in length and width orientation. It was observed in the projections that the sharp points were usually located at the position responding to the end or start of the edge. Singulative theory of detecting signal based on wavelet transform was applied to the detection of this kind of sharp points. The method was also analyzed in detail on how to select the proper wavelet and the proper scale to orientate sharp points.
