Embodiment Construction

[0039] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0040] According to an embodiment of the present invention, an adaptive division method of pulse array coding is proposed. The difference from the coding tree unit and coding unit in traditional video coding is that in the coding of traditional video, the form of video is an image sequence (the "image" here is also called "frame"), and the division of traditional video When dividing a two-dimensional image into multiple two-dimensi...

Abstract

The invention provides an adaptive partitioning method for pulse array coding. The method comprises the following steps: time-space pulse information is acquired by a time-space signal sensor to forma pulse array; the pulse array is partitioned into multiple coding tree cubes; each coding tree cube is partitioned into coding cubes through multi-level partitioning until being partitioned to the maximum depth; the performance of the coding cube structure before partitioning each time is compared with the performance of the coding cube structure after partitioning to decide whether or not to conduct code cube partitioning; and partitioning structures of the coding tree cubes and the coding cubes are determined, and partitioning results are output. According to the method, an adaptive partitioning mode for a time-space pulse array signal with both time and space is proposed according to a partitioning thought for a coding structure in traditional video coding; and by means of partitioningin the space domain and the time domain, the operated area range is provided for the follow-up compression process.

Description

technical field [0001] The invention relates to the technical field of information coding, in particular to an adaptive division method of pulse array coding. Background technique [0002] Traditional video is collected by a camera using a charge-coupled device (Charge, -coupled Device, CCD) or a complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor, COMS), to obtain an image sequence of the same size with a fixed time interval. In the sequence, the image of each sampling point becomes a frame. The compression process of traditional video includes prediction, transformation, quantization and entropy coding, etc. In these steps, operations are performed on a part of each frame, so as to remove redundancy and reduce the amount of data. In the current encoding and decoding, for the selection of the above-mentioned regions, the form of quadtree division is mostly adopted, and the size of the operated region is determined according to the texture dist...
