A method and a system for adaptively restoring the true color of an image

Abstract

The invention provides a method and a system for adaptively restoring the true color of an image. The method comprises the following steps: performing training according to the pixel gray value of a reference object in a training set and the true color information of the reference object to obtain the corresponding relationship between the pixel gray value of an image captured under the conditionof environmental spectral information and the true color information of the image; receiving a current photographed image of the imaging device and current ambient spectral information of a spectral probe balanced with the center of the optical axis of the imaging device; analyzing the current photographed image to obtain the gray value of each pixel of the current photographed image; obtaining apixel gray level compensation value of the current photographed image according to the corresponding relationship between the pixel gray level value of the photographed image under the current environmental information and the true color information of the image; obtaining a restored image of the currently captured image according to the pixel gray compensation value of the currently captured image and the gray value of each pixel of the currently captured image. The invention can quickly and accurately restore the image color.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method and system for adaptively performing true color restoration of an image. Background technique [0002] Security monitoring is very important for maintaining social stability, enhancing urban public security management, and improving people's sense of security and happiness in life. In various interactive scenarios, the security system can record and store scene events in real time through images, which is convenient for subsequent viewing and restoration of the scene at that time, and provides a large amount of original data and evidence for tracing illegal and criminal acts. [0003] However, most of the current security systems still use traditional imaging equipment, that is, RGB images or videos are generated by fixed optical filters and band response functions. The RGB image or video generated by the traditional imaging system conforms to the ima...
