Joint channel–spatial entropy modeling for efficient visual coding

Deep learning-based methods have recently achieved impressive performance in lossy image compression, surpassing traditional codecs in rate-distortion efficiency. However, current learned compressors still struggle to fully exploit crossed-channel redundancies and long-range spatial dependencies in...
