this method aimed at avoiding the limitation of liner de-interlace and motion adaptation de-interlace algorithm, and put emphases on image detail protection and noise elimination, at the same time consider the cost of hard ware and operation spending . the first step of this method is in the motion-detection unit, we add an adaptation median filter in order to protect image details and eliminate noise, so the motion-detection result more precise . the second step is that adopting bidirectional block matching motion-estimation, this way can get more exact motion-vector, at the same time can reduce the operation spending and improve robust
針對已經(jīng)提出的線性去隔行和運(yùn)動自適應(yīng)去隔行算法存在的缺陷,著重在保護(hù)運(yùn)動圖像細(xì)節(jié)和噪聲的濾除方面進(jìn)行考慮,并兼顧硬件開銷和運(yùn)算時(shí)間,提出了在運(yùn)動補(bǔ)償去隔行過程中的前期運(yùn)動檢測單元加入自適應(yīng)中值濾波保護(hù)圖像細(xì)節(jié)和濾除噪聲,使檢測出的靜止和運(yùn)動像更加準(zhǔn)確,同時(shí)采用雙向塊匹配運(yùn)動估計(jì),得到更加精確的運(yùn)動矢量。
