Abstract: Disclosed are a quantizing method for a latent vector and a computing device for performing the quantization method. A quantizing method of a latent vector includes performing information shaping on the latent vector resulting from reduction in a dimension of an input signal using a target neural network; clamping a residual signal of the latent vector derived based on the information shaping; performing resealing on the clamped residual signal; and performing quantization on the resealed residual signal.

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.

Abstract: Disclosed herein are a method, an apparatus and a storage medium for encoding/decoding using a transform-based feature map. An optimal basis vector is extracted from one or more feature maps, and a transform coefficient is acquired through a transform using the basis vector. The basis vector and the transform coefficient may be transmitted through a bitstream. In an embodiment, one or more feature maps are reconstructed using the basis vector and the transform coefficient, which are decoded from the bitstream.

Abstract: Disclosed herein are a method, apparatus, and storage medium for image encoding/decoding. Selective compression learning of latent representations for variable-rate image compression is used for the method, apparatus, and storage medium. A selective compression method that partially encodes latent representations in a completely generalized manner for deep-learning-based variable-rate image compression is disclosed in embodiments. The methods of the embodiments adaptively determine essential representation elements for compression at different target quality levels.
