Free Lossless Image Format (FLIF) is a work-in-progress lossless image format based on MANIAC compression. FLIF claims to outperform PNG, FFV1, lossless WebP, lossless BPG and lossless JPEG 2000 in terms of compression ratio on a variety of Inputs. FLIF supports a form of progressive interlacing (a generalization of the Adam7 algorithm), which means that any partial download of a compressed file can be used as a reasonable lossy encoding of the entire image. The format was initially announced publicly in September 2015, with the first alpha release occurring about a month later, in October 2015.〔(【引用サイトリンク】url = https://github.com/FLIF-hub/FLIF/releases/tag/v0.1-alpha )〕 For compression, FLIF uses MANIAC (Meta-Adaptive Near-zero Integer Arithmetic Coding), a variant of CABAC where the contexts are nodes of decision trees which are dynamically learned at encode time. == See also == * WebP * BPG * Lossless compression 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Free Lossless Image Format」の詳細全文を読む スポンサード リンク
