摘要
Provided is a process for compressing data that includes: obtaining data to be compressed; compressing the data with a first DCT compression algorithm to obtain a first DCT amplitude matrix; compressing the data with a second DCT compression algorithm to obtain a second DCT amplitude matrix, the second DCT compression algorithm compressing the data more than the first algorithm; modifying the second DCT amplitude matrix based on a value in the first DCT amplitude matrix.
