Signal lamp color effect enhancement processing method and apparatus thereof

Abstract

The invention discloses a signal lamp color effect enhancement processing method and an apparatus thereof. The method and the apparatus are applied to an image processing system. The method comprises the following steps of extracting a reference RGB value from a signal lamp image; calculating color components of colors of all the pixels in a signal lamp area, wherein the colors match with display colors in the signal lamp area; then according to the calculated color components, carrying out corrosion processing on the signal lamp image, carrying out binarization processing on the signal lamp image which is not processed by a corrosion algorithm and on the signal lamp image which is processed by the corrosion algorithm and acquiring a different area of twice binarization processing; and taking the reference RGB value as a reference, selecting different color order parameter, calculating replaced RGB values of a foreground area and the different area acquired through the corrosion algorithm processing respectively, and then using a replaced RGB value of each pixel to replace an original RGB value of each pixel. The invention also discloses a signal lamp color effect enhancement processing apparatus. In the invention, signal lamp colors in a signal lamp image are easy to distinguish, an effect is nature and a lamp eye contour is clear.

Description

technical field [0001] The invention relates to the field of post-processing of images. More specifically, the present invention relates to a signal light color effect enhancement processing method and device. Background technique [0002] With the development of the current electronic police system, users have higher and higher requirements for camera image effects. However, it is a common problem of major security manufacturers that the current camera sensor (sensor) is not sensitive to the signal light. In some scenarios, it is difficult to distinguish the color and shape of the signal lights in the camera video and pictures, and this is especially serious for customers such as traffic police departments. Therefore, for the image side effects brought by this sensor, it is necessary to provide a solution on the software side—enhance the color presentation of the signal light according to the actual detected signal light state during post-processing, restore the real color...

Problems solved by technology

This solution only pays attention to the modification of the color, regardless of the influence of the actual scene such as day and night, surrounding lighting, camera exposure, etc. on the presentation of the signal light, and uses a fixed color to modify the color of the signal light. It will lead to opaque traffic light areas, blurred outlines, and single colors, giving people a sense of visual unreality. In the electronic police system, it will be suspected of being tampered with by PS if the violation is determined
