例句與用法

in fact, scaling technology is an essential component in many image / video processing such as to magnify / minify still image, to achieve special effect like picture-in-picture, to compress or transform digital video with spatial scalability etc . in this thesis we mainly employ this technology in video transcoding, which is a powerful but computationally intensive tools to convert one kind of video format into another, meeting different demand such as lower bitrates or various display terminals . in sum, there are two kinds of scaling schemes : one is in spatial domain and the other in transform domain . the scheme in transform domain can provide very good performance, that is, efficient computation and desirable image quality, whereas it has some disadvantage which is impossible or hardly to o vercome, especially some scenarios require arbitrary ratio zoom in horizontal and vertical, and excellent visual effect
兩種方法都各有其利弊：變換域的方法是利用現(xiàn)有常用的視頻壓縮方案都是基于dct這個(gè)特點(diǎn)，所以可以直接在變換域做處理，這樣可以節(jié)省大量的計(jì)算，但其缺點(diǎn)是由于dct是基于塊的變換，如88，所以很難找到一種方案可以進(jìn)行任意比例的縮放，尤其是在縱橫縮放比例不一致的情形，但這對諸如hd縮放到sd和空域分級的壓縮方案來說尤為重要，基于空域?yàn)V波的方法卻沒有這樣的限制，同時(shí)可以保證縮放后的圖像的質(zhì)量遠(yuǎn)高于基于變換域的方法，為了達(dá)到高的縮放質(zhì)量，就不可避免導(dǎo)致計(jì)算量過大。
