• Existing state-of-the-art learned image compression methods based on CNNs or Transformers are inherently rigid due to fixed receptive fields and static connectivity patterns.limitation 70%
  Evidencepartial

  Most state-of-the-art (SOTA) learned image compression (LIC) methods are based on CNNs or Transformers, which are inherently rigid. Standard CNN kernels and window-based attention mechanisms impose fixed receptive fields and static connectivity patterns

  Implicationpartial

  The abstract explicitly states this limitation of current methods.
