摘要
目前 ,二值图像压缩主要采用无损压缩方式 ,压缩倍数低。针对具有相同背景的表格图像 ,借鉴在运动图像压缩中效果很好的模型基压缩方法 ,提出将表格图像的相同背景建立成二维模型 ,将表格图像中的不同内容作为运动参数进行编码 ,解码时再将图像进行合成的方法。
At present, binary image compression is still in the stage of lossless encoding with low compression ratios. In allusion to form images with the same context, a sepcial method which uses the same context of form images as 2D model and the differentia as moving parameters is proposed according to the model-based coding with moving image. The same part and the differentia are combined when decoding. Experiments prove that the compression efficiency is perfect.
