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: Provided is a method for a plurality of processing elements to filter a plurality of pixel blocks in a plurality of picture partitions for a single frame image. The method for filtering pixel blocks includes: checking the status of a second boundary pixel block adjacent to a picture partition boundary, the second boundary pixel block being one of a plurality of pixel blocks in a second picture partition and neighboring a first boundary pixel block in a first picture partition, the first boundary pixel block neighboring the picture partition boundary; selecting a filtering area for the first boundary pixel block based on the status of the second boundary pixel block; and filtering the filtering area for the first boundary pixel block.
