Embodiment Construction
[0012] The present invention will be described in detail below in combination with specific embodiments.
[0013] The nighttime image enhancement method with highlight suppression of the present invention is implemented according to the following steps:
[0014] Step 1. Convert the color system of the input night image
[0015] In order to better maintain the color information of the image, during the initialization process, the input night image is converted from the RGB color system to the HSV color system, the H and S channel information of the color information is retained, and only the brightness channel V is processed. Since color system conversion is a prior art, it will not be repeated here.
[0016] Step 2. Perform pre-enhancement processing on the converted image in step 1
[0017] For the night image under the HSV color system processed in the previous step, the Retinex enhancement method based on the time-domain recursive filter is used. The Retinex enhancement m...
