lossless compression

基本解釋

Lossless compression is fine, but reformatting and storing received data for a small percentage gain in space in a large database will cause more issues than it's worth.
無(wú)損的壓縮雖好，但是爲(wèi)了在大型數(shù)據(jù)庫(kù)中節(jié)省少量的空間而重新格式化和存儲(chǔ)接收的數(shù)據(jù)，會(huì)導(dǎo)致更多問(wèn)題，實(shí)屬不值。
Visual lossless compression is loss compression in the store of information, but human vision cant feel the loss of information, so it cant affect the medical diagnosis.
眡覺(jué)無(wú)損壓縮在信息存儲(chǔ)上實(shí)際是有損壓縮，但人類(lèi)眡覺(jué)系統(tǒng)竝不能察覺(jué)出這種圖像信息量的損失，因而不影響臨牀診斷。
Lossless compression bounds of images naturally acquired by various imaging sensors are estimated using a practical method based on multi scale conditional entropy and memory measurement.
爲(wèi)估計(jì)利用各類(lèi)成像傳感器自然獲取圖像的無(wú)損壓縮極限，提出一個(gè)利用多尺度條件熵和記憶性度量的實(shí)用方法。

The RAW data format provides pure data for high-resolution images, and uses lossless compression for more compact, yet uncompromised, data files.
