Intelligent inter-frame coding operation platform

Abstract

The invention relates to an intelligent inter-frame coding operation platform, and the platform comprises a monitoring spherical device which is disposed at a monitoring place and is used for recording a monitoring video of a monitored scene, so as to obtain a plurality of continuous monitoring scene images on a time axis; a size selection device which is used for executing the following operations on each target area: determining the size of a search window for executing inter-frame motion vector analysis on a target corresponding to the target area based on the size of the target area, and setting the size of a search window for performing inter-frame motion vector analysis on a target which does not belong to a moving target to be zero. The intelligent inter-frame coding operation platform is flexible in design and wide in application. As the moving target motion search window for executing the inter-frame coding can be flexibly customized according to the target size and the targettype of the monitoring scene, reliable motion reference data is provided for subsequent image coding processing while excessive operation resources are not occupied.

Description

technical field [0001] The invention relates to the field of inter-frame coding, in particular to an intelligent inter-frame coding operation platform. Background technique [0002] The quality of the reconstructed image at the receiving end is measured by the distortion relative to the original image. The objective measure of distortion is generally represented by the mean square error between the original image sample and the reconstructed image sample at the receiving end after image coding. The subjective measure of distortion is human visual experience, which is a decisive evaluation of the quality of the reproduced image. When studying image coding, both subjective and objective distortion measures are often used. [0003] A moving image can be regarded as a brightness distribution in a three-dimensional space determined by plane coordinates i, j and time coordinate t. There is a correlation between adjacent pixels (also known as pixels) in the same plane and betwee...

Problems solved by technology

[0005] In the prior art, the inter-frame coding mode used for images of various scenes is exactly the same, without taking into account the types and sizes of different targets in the monitoring scene, for example, if a large search window is set for a small-sized moving target Performing inter-frame motion capture, although reliable motion capture results can be obtained, but a lot of coding computing resources are wasted. At the same time, if the motion capture of the search window is performed on a static target, more coding is also wasted. computing resources
