I'm echoing a couple of replies before me, but I'll give concrete examples - MP3, JPEG, and H.264 are all lossy task-specific compressions. Lossless compression includes FLAC and TIFF.
For genetic data, HapZipper beats general-purpose compression.

So, yes, actively researched, but you've got to pick a specific task that makes sense. Even small niches are viable; I made a task-specific compressor to strip the essential numbers out of a remote sensor report to make it small enough to squirt to a satellite.
- forgotusername6 5y agoVideo compression algorithms are fascinating. Choosing the correct color space and reducing bit count because the human eye doesn't see color as well, using discrete cosine transform to "group together" the important parts of an image, using diffs from previous and future frames, using diffs from movement in the image. There are so many techniques.
