Abstract

Lossless image compression is vital for missions with limited data transmission bandwidth. Reducing file sizes enables faster transmission and increased scientific gains from transient events. This study compared two image compression algorithms, CCSDS 122.0 and JPEG 2000, used in the European Space Agency Comet Interceptor and Hera missions respectively, in varying scenarios. The performance analysis for both algorithms consists of compressing simulated asteroid images in the visible and near-infrared spectral ranges. In addition, all test images were noise-filtered to study the effect of the amount of noise on both compression ratio and speed. The study found that JPEG 2000 achieved consistently higher compression ratios and benefited from decreased noise more than CCSDS 122.0. However, CCSDS 122.0 produced comparable results faster than JPEG 2000 and is substantially less computationally complex. These results not only support previous findings while contributing valuable knowledge to the behavioral characteristics of both algorithms but also provide insight for entities planning on using either algorithm for on-board of planetary missions.
