摘要:	Two techniques for both zooming and smoothing digital Chinese character patterns are presented. In this paper, zooming by Discrete Cosine Transform (DCT) technique is proposed for achieving binary and grey-level digital character patterns in different resolutions. Where the grey-level character patterns are shrunk in a lower resolution of 12 * 12 pixels this can be achieved in a monitor display more clearly than those shrunk by traditional zooming techniques; while zig-zag phenomena appeared equally in the character patterns, expanded by both zooming techniques. Then, a smoothing technique using morphological operations is proposed to smooth the zig-zag patterns expanded by traditional zooming techniques. Therefore, zig-zag phenomena can be substantially alleviated, and high quality character patterns can be produced.
