Abstract: Disclosed herein are a method, an apparatus, and a storage medium for image encoding/decoding using geometric partitioning. Partitioning of a block may be determined using directionality in a block. A straight line is detected in the block, some of partitioning methods available for the block are excluded depending on the type of the detected straight line, and only the remaining partitioning methods are limited to a target of selection for encoding and/or decoding on the target block. Further, the mode of a geometric partitioning mode may be determined using directionality in the block. A straight line is detected in the block, some of available modes of a geometric partitioning mode are excluded depending on the type of the detected straight line, and the remaining modes are limited to the target of selection for encoding and/or decoding on the target block.

Abstract: There are provided an apparatus, method, system, and recording medium for performing selective encoding/decoding on feature information. An encoding apparatus generates residual feature information. The encoding apparatus transmits the residual feature information to a decoding apparatus through a residual feature map bitstream. The residual feature information is the difference between feature information extracted from an original image and feature information extracted from a reconstructed image. Feature information of the reconstructed image is generated using the reconstructed image. Reconstructed feature information is generated using the feature information of the reconstructed image and reconstructed residual feature information.
