Title The one-key quality enhancement and motion analysis for Public security image and video :one-key quality enhancement and correction techniques
Abstract Due to the limitation of complex environment and the objective conditions of imaging system,image and video are affected by fuzzy、noise、color distortion and so on in public security.This paper investigates the one-key quality enhancing techniques for low-quality image and video.The main contributions are as follows: Firstly,we design and complete an local self-adapting color enhance algorithm. Experimental shows that this algorithm peforms better than global algorithm. Secondly,we design and complete an one-parameter lens distortion correction algorithm.we use this algorithm to correct lens distortion in image and video. In order to complete this algorithm,we establish a mathematic model for radial distortion.Automatic estimation is performed for parmeter. Thirdly,we design an algorithm wto track and agnificate the interested objects synchronously.This algorithm is base on optical flow. Motion compensation is performed in the interested region use centroid algorithm.Experimental results show that effectiveness of the algorithm. Fourthly,we complete the pluggable development and integration of algorithms. The integrated software is designed as the idea of one-key process.we can call the function in plugin through the software.
