Problems solved by technology

However, the light migration of such a model simply performs a simple statistical calculation on the color and brightness information of the source and target images globally, without considering the local unevenness of the color and brightness distribution.
Therefore, the color brightness consistency between the migrated image and the source image is poor, and the migrated image has the problem of uneven local distribution of image color brightness.
[0005] Although the above method can solve to a certain extent the problem of the difficulty in identifying pedestrians due to different illumination intensities of different cameras, there are still big problems, and it cannot solve the loss of local color information caused by the use of global statistical image brightness information and eventually lead to migration effects. bad situation

Abstract

The invention relates to a specified adaptive illumination migration method and system in a cross-camera scene, and the method comprises the steps: carrying out the close image clustering of a targetimage and a source image according to a fuzzy clustering algorithm, carrying out the local color brightness migration between clustered images, and introducing a membership factor to improve the colorbrightness migration effect. According to the invention, the illumination difference of images under different cameras is weakened, and the adverse effect caused by the illumination difference is reduced.

Description

technical field [0001] The invention relates to the field of intelligent security technology, in particular to a method and system for specifying self-adaptive light migration in a cross-camera scene. Background technique [0002] With the continuous development of the economy, people's demand for safety is increasing day by day. Therefore, the application range of intelligent surveillance video in the field of security is constantly expanding, and related video intelligent processing technologies such as pedestrian tracking and retrieval have become the focus of current research. Related studies range from single-camera to multi-camera and from single-pedestrian to multiple-pedestrian development. In the current research results, image processing under a single camera and intelligent monitoring technology under a single pedestrian have developed rapidly and achieved certain results, but the results in the field of multiple cameras or multiple pedestrians are not so satisfa...
