The Emergence, Development and Evolution of News Reports on Computer-Aided Image Abstraction Algorithms

This paper proposes a computer-aided image abstraction rendering algorithm to enhance contrast. First, the structure tensor smoothing technology is used to generate a smooth, continuous, and feature-maintained characteristic flow field, and then based on the flow field, the image is subjected to adaptive smoothing along the edge tangential flow direction and contrast enhancement processing along the gradient direction. The computer-aided technology is the cultural capital obstacle faced by reporters, and the acquisition of "raw data" is the biggest problem for most domestic reporters entering the field of data journalism. Based on this, the journalism and communication community has the responsibility to explore the theory of "data journalism" and give the practice and operation mode of data journalism.
