Introduction

Standard Development Background and Technology Evolution

With the popularization of intelligent video analysis systems in the public security field, the total number of cameras built in the National Snow Bright Project from 2018 to 2022 has reached 40 million. The original video needs to be processed by 12 types of core processing technologies to meet the actual combat needs. This standard has unified the coding system of processing types for the first time.

Technical Analysis of Code Table

Code	Technology Type	Typical Application Scenarios	Algorithm Complexity
02	Defogging	Traffic Monitoring in Foggy Days	Medium
08	Super-resolution Reconstruction	Suspect Facial Enhancement	High
13	De-shaking	In-vehicle Mobile Video	Low

Key Technology Comparison

Differences between low illumination enhancement (05) and wide dynamic enhancement (07):

Low illumination: solves the problem of decreased signal-to-noise ratio caused by insufficient light, suitable for night monitoring
Wide dynamic: balances the overly bright/dark areas in the same picture, suitable for backlit scenes

Implementation Suggestions

1. It is recommended to use the code conversion middleware of the video analysis server when connecting the system
2. Code 99 should be used in conjunction with the extended description document
3. Implement in conjunction with GA/T 1399 "Technical Requirements for Video Image Analysis Systems"
