电视图像的视觉传达设计研究

针对高清电视数字图像边缘对比度低、清晰显示难度大的问题,提出考虑视觉传达效果的二维灰度电视图像直方图边缘显示方法.首先对包含大量扰动信息和各类噪声的电视图像进行预处理,识别信号模式并进行特征提取;根据电视图像特征及灰度梯度在图像边缘的响应,获取直方图的统计特征并进行分块处理,形成二维灰度图像的直方图;搜寻出二维灰度图像直方图与电视数字图像边缘的内在关联性,实现对电视图像边缘的精确显示.实验结果证明,提出的电视图像边缘显示方法能够获得更好的视觉传达效果.

Research on Visual Communication Design of TV image

Aiming at the problem of low edge contrast and difficulty of clear display of HDTV digital image,this paper proposes a histogram edge display method of two-dimensional gray TV image with visual communication effect.First of all kinds of noise and disturbance information contains a large number of TV image preprocessing,feature extraction and pattern recognition signal;according to the characteristics of the image and gray image edge gradient in response to TV,get the histogram statistical features and block processing,forming a two-dimensional gray image histogram;searching for relevance of two-dimensional gray image histogram TV and digital image edge,to achieve accurate display of TV image.The experimental results show that the proposed image edge TV display visual effect method can get better.
