摘要
在处理光照不均匀的图像分割时用常用的阈值分割方法不能得到良好的分割效果,通过分析图像特征及对小波分析理论的研究,提出采用小波滤波器将滤波以后的低通图像作为图像的浮动阈值进行二值化,获得了比较理想的效果。该算法在枪支在线OCR识别系统中得到实际应用。
A good segmentation effect cannot be obtained with the threshold segmentation method that always applied to processing the image segmentation of the non-uniformly illuminated image. Through analyzing image characteristics and research of wavelet analysis theory, using the low pass image after filtering with wavelet filter as floating threshold and carry out binarization, a relative ideal effect is obtained. The algorithm has been practically applied to an on-line optical character recognition system for guns.
