摘　　要：图像增强是对数字图像的预处理,对图像整体或局部特征能进行有效地改善。针对传统直方图均衡算法存在的动态范围小、细节丢失及对比度不自然等问题,提出结合直方图规定化的改进算法。仿真结果表明,经过规定化的灰度级调整后,图像亮度及清晰度均有所增加,层次感增强,细节部分也基本达到预期效果,且复杂度相当,具有实际应用价值。Image enhancement is a digital image preprocessing,feature the image as a whole or in part,could be effectively improved.Traditional histogram equalization algorithm for the dynamic range of existing small,detail lost and the contrast unnatural and other issues,proposed a histogram specification of the improved algorithm.Simulation results show that,after the provisions of the gray-scale adjustment,the image brightness and clarity have increased,and layered enhancement,details of some basically achieve the desired results,considerable complexity and practical applications.
