如何在图像有损压缩过程中保持图像的自动目标识别性能，是军事图像通信领域面临的重要挑战。

JPEG is a lossy compression, which means what you get out is not what you put in. Specifically, instead of all being hard black, my transparent area was in a range of black, such that I needed to filter 0,0,0, through to 35, 35, 35 to get the masking effect I needed.

Almost all video codecs use lossy compression to minimize the huge amounts of data associated with video.

几乎所有的视频编译码器都采用有损压缩，最小化与视频相关的数据量。

Try to avoid the JPEG graphics format, and other formats that use lossy compression, as they are optimized for photographic images.

尽量避免JPEG图形格式和其他格式，使用有损压缩，因为它们是优化的摄影作品。
