Embodiment Construction

[0030] Some implementations of the current subject matter include partitioning rectangular regions into more computationally efficient flexible geometric regions. Geometric partitioning may be performed at the block level (eg, 2x2, 4x4, etc.) rather than the pixel level. In some embodiments, geometric partitioning at the block level may include partitioning the block into non-overlapping and rectangular sub-blocks (e.g., 2x2, 4x4, etc.), and then partitioning the block into Non-rectangular areas, which may include multiple rectangular sub-blocks. Geometric partitioning at the block level may be determined (eg, implemented) by signaling the start and end sub-block indices for partitioning the block. A straight line connecting signaled sub-blocks may characterize a partition. Block-level geometric partitioning can reduce complexity and increase compression efficiency.

Abstract

A decoder includes a circuitry configured to receive a bitstream, determine whether a block level geometric partitioning mode is enabled, determine a partitioning of a block into a first region and asecond region, and reconstruct the pixel data of the block. Related apparatus, systems, techniques, and articles are also described.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 688,552, filed June 22, 2018, the entire contents of which are expressly incorporated herein by reference. technical field [0003] The topics described in this article relate to video compression, including decoding and encoding. Background technique [0004] A video codec may include electronic circuitry or software that compresses or decompresses digital video. Convert uncompressed video to compressed format and vice versa. In the case of video compression, a device that compresses video (and / or performs some function thereof) may generally be referred to as an encoder, and a device that decompresses video (and / or performs some function thereof) may be referred to as a decoder. [0005] The format of the compressed data may conform to standard video compression specifications. Compression can be lossy, with the compressed video missing...
