摘要
针对在产品包装设计图像处理过程中未考虑图像在人眼视觉成像限制的问题,文中提出一种基于人眼视觉特性的包装设计图像处理算法,以实现产品包装图案的增强。通过对人眼的生理构造、视觉成像系统的分析,将人眼视觉注意机制融入到图像灰度直方图的构建过程中,形成图像信息直方图以突出图像中含有重要信息的部分。在此基础上,将人眼感知特性融入到增强算法中,以减小直方图中主灰度级的信息量。同时,结合VHIST制定人眼感知特性的图像特征评价方法。通过与其他文献的结果对比可知,文中所述的图像处理算法可以有效地实现图像增强效果,图像中的重要信息得到了突显,在对比度等指标上的测试结果优于参考文献。
In allusion to the problem that the limitation of human visual characteristics is not considered in the process of image processing of the product packaging design,a packaging design image processing algorithm based on human visual characteristics is proposed to enhance the product packaging pattern.By means of the analysis of the physiological structure and the visual imaging system of the human eye,the visual attention mechanism of the human eye is integrated into the construction process of the image gray histogram to form the image information histogram,so as to highlight the important information part of the image.On this basis,the human visual characteristics are integrated into the enhancement algorithm to reduce the amount of information of the main gray level in the histogram.At the same time,an image feature evaluation method of human visual perception is developed by combing with VHIST.In combination with the results of other literatures,it can be seen that the image processing algorithm described in this paper can effectively achieve the effect of image enhancement,the important information in the image has been prominent,and the testing results on contrast ratio are better than those in the references.
