Abstract
Disclosed herein are a method, an apparatus and a storage medium for image encoding/decoding. There is proposed a novel NN-based spatially scalable image compression method, called Compression with Arbitrary-scale Spatial Scalability (COMPASS), which supports arbitrary-scale spatial scalability. COMPASS may have a very flexible structure in which the number of multiple layers and respective scale factors of the multiple layers can be arbitrarily determined during inference. In order to reduce the spatial redundancy between adjacent layers for arbitrary scale factors, COMPASS may adopt an inter-layer arbitrary scale prediction method, called a Local Implicit Filter Function (LIFF) based on implicit neural representation.
