摘要
针对直接对灰度图像或二值图像求不变矩的计算量大,目标不够明确的的缺点,提出了先对图像进行预处理,再进行基于图像轮廓边缘的统一Hu不变矩计算,并加上了图像离心率的特征量,最后利用这些特征量进行图像识别的算法过程。实验表明此算法运算效率高、识别准确,能用于图像实时处理。
To improve the efficiency and precision in the image processing for asking the moment invariants,a utility image recognition algorithm is put forward. It does the pre-processing for the image and computes the moment invariants based on the image edge and the eccentricity character. Finally,it uses these characters to make the image recognition. It is proved by the experiment that the algorithm is very effective and can recognize the destination exactly. It can be used in real time processing.
