| 摘 要： | 将直方图均衡化看作典型的不适定问题,提出了可调直方图均衡化的正则化解释,以及为了获得较好的图像增强效果并给出其改进措施.首先,对可调直方图均衡化方法所对应的目标函数进行简化,得到了基于信息能量作为正则项的可调直方图均衡化崭新解释;其次,考虑到信息熵与信息能量之间呈对偶关系,于是获得了一种基于信息熵作为正则项的可调直方图...

| Abstract: | In view of histogram equalization regarded as typical ill-posed problem,the adjustable histogram equalization method is explaned by regularization theory,and its improvement is proposed in order to obtain the better effect of image enhancement.Firstly,the objective function of adjustable histogram equalization method is simplified and explaned by means of information energy as a regular item.Secondly,in consideration of the dual relationship between information entropy and information energy,the new adjusta... |
