IMAGE DECODING METHOD AND APPARATUS USING PROJECTION-TYPE BASED QUANTISATION PARAMETERS IN IMAGE CODING SYSTEM FOR 360-DEGREE VIDEO

WIPO Patent Application WO/2019/009600

A1

An image decoding method that is performed by a decoding apparatus of the present invention comprises the steps of: receiving 360-degree video information; deriving a projection type of a projected picture based on the 360-degree video information; deriving a weight map of the projected picture based on the projection type; deriving quantisation processing units of the projected picture; deriving DAQP for the respective quantisation processing units based on the weight map; and decoding the respective quantisation processing units based on the DAQP.
