想要取代 JPEG 的 BPG (Better Portable Graphics)

雖然是有點久的消息了,但還是拿出來講:「BPG Image format」。

在「BPG Image Comparison」這頁可以直接看到一些比較,在「BPG/JPEG comparison on the Lena picture」可以看到經典的萊娜圖比較。

很明顯 BPG 比 JPEG 好很多,而又比 WebP 更上一層樓。但是看到這個部份就皺眉了:

Based on a subset of the HEVC open video compression standard.

最後面也有提到 HEVC (High Efficiency Video Coding) 的專利問題:

Some of the HEVC algorithms may be protected by patents in some countries (read the FFmpeg Patent Mini-FAQ for more information). Most devices already include or will include hardware HEVC support, so we suggest to use it if patents are an issue.

繼續觀望下去 :o
