摘要
在图像信息的编码过程中 ,由于量化不精确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 coded process easily cause blur in the decoded image because the component of high frequency is not measured accurately and part of that is lost. By interpolation methods we can add the pixels into TV image, change alternative scanning into progressive scanning and improve the image definition.
