Impact of CCSDS-IDC and JPEG 2000 Compression on Image Quality and Classification

Table 1

Compression ratio (CR, expressed as x : 1, e.g., 5 : 1) and distribution among bands: two approaches were used. Moreover bit rates in bpppb are also indicated (compressed images inside the simulator have a bit-depth of 16 bpppb).
