Zachary Chavis Compression/Decompression

Zachary worked on a compression and decompression algorithm to enable the transfer of image data to/from orbit. This work, in conjunction with the aforementioned super-resolution work, focuses on ensuring that the compressed and subsequently decompressed data is still useful for various image processing applications.

Delia Davila Super-Resolution

Delia evaluated the impact of compression on the results obtained from super-resolution algorithms. The goal is to determine the trade-offs as compression is required to move significant amounts of image data from a small spacecraft in orbit to the Earth.
