Abstract: The present invention relates to image encoding and image decoding. A method for encoding images according to the present invention comprises the steps of: acquiring division information from peripheral blocks of an encoding target block with respect to the peripheral blocks; predicting the division of the encoding target block on the basis of the acquired division information; encoding information on the difference between the practical division information of the encoding target information and the predictive division information predicted in the predicting process; and transmitting the encoded information. The present invention can encode/decode the division information of the encoding/decoding target blocks using the information about the peripheral blocks.

Abstract: Provided are an image encoding method and device. When carrying out image encoding for a block within a slice, at least one block in a restored block of the slice is set as a reference block. When this is done, the encoding parameters of the reference block are distinguished, and the block to be encoded is encoded adaptively based on the encoding parameters.

Abstract: The present disclosure relates to a method and apparatus for representing dynamic neural radiance fields from unsynchronized videos. A method of acquiring a video at an arbitrary viewpoint based on a dynamic neural radiance fields model according to an embodiment of the present disclosure may comprise: inputting one or more videos acquired from one or more views for one scene into the dynamic neural radiance fields model; inputting a time embedding for the one or more videos into the dynamic neural radiance fields model; and rendering the video at the arbitrary viewpoint based on color information and density information output by the dynamic neural radiance fields model. Herein, time synchronization related to the time embedding may be performed by applying an individual time offset learned for each view, for the one or more views.
