摘要
在模式识别中,二值化效果的好坏直接影响着识别率。针对几种常用的图像二值化自动选取阈值方法,通过计算机仿真试验比较,提出一种全局阈值法和局部阈值法相结合的新的图像混合阈值二值化方法。
In pattern recognition, the effect of b inarization directly affects the recognition rate. Through experiment with several general threshold selection methods, the results were analyzed. A new method of hybrid threshold selection is put forward based on the combination of global thresholding and local thresholding.
