It would be more interesting to get the compression algorithm from Google's WebP or HVEC as used by the BGP image format (http://bellard.org/bpg/) into TIFF.

WebP (VP8 derivative) does not work for large images, but it would work great in TIFF with smaller strips or tiles. HVEC currently has patent issues but may become common as more hardware comes with support for it.

Both of these compress smaller for a given quality than ordinary JPEG.
