In view of the histogram equalizing algorithm to enhance image in digital image processing,an improved histogram equalizing algorithm is proposed for image enhancement. Combining with the characteristic of global histo-gram equalization and local histogram equalization,histogram equalization algorithm is improved with incremental his-togram equalization from the processing method. The experimental results indicate the proposed method can enhance images more effectively and eliminate image noise,which provides the foundation for the following effective recogni-tion feature,and simultaneously improves the effect of image target recognition.
