摘要
在图像信息的编码过程中,由于量化精度不高造成高频成分的损失导致图像不清晰。通过内插的方法增加电视图像的像素数,把隔行扫描改造成逐行扫描,达到提高图像清晰度的目的。
Image codec process easily causes blur in the decoded image because of that the quantization accuracy is not high enough and part of the high frequencies is lost. By interpolation methods we can add pixels to TV image, change interlaced scanning into progressive scanning and improve the image definition.
