A small-size Chinese font display by perception-based method

摘要

This paper presents a perception-based method for Chinese fonts at a size small than 20 points to achieve a high-quality display. The basic idea behind the proposed method is to adopt human visual-based grid-fitting rules with the gray-scaling strategy. The major procedures include supersampling, adjusting the position and width of strokes, grayscale filtering and subsampling. The experimental result shows that the jagged edge induced by the coarse resolution can be removed and the rendition of character details and the contrast are also improved, this reveals that the character's clearness and smoothness can be enhanced for a higher legibility with comfortable reading.
