Problems solved by technology
[0002] At present, due to the presence of fog, haze or other particles in the outdoor environment, the gray value of the area covered by the fog in the captured image is high, the image is white, the outline of the scene is blurred, and the image feature extraction is difficult, which leads to image distortion and greatly affects the vision. As a result, it brings difficulties to real-time applications of outdoor work systems such as monitoring, intelligent navigation, and drone reconnaissance, and affects people's normal life

Embodiments of the present invention disclose an image segmentation method and a terminal. The image segmentation method may include: acquiring an image to be processed; acquiring the depth distance of each target object in the image to be processed; according to the image segmentation in the image to be processed. According to the depth distance of each target object, the image to be processed is divided into a foreground image and a background image; the background image is dehazed; the dehazed background image and the foreground image are synthesized to obtain the defogging process image after. The method can segment the image to be processed into a background image and a foreground image, perform defogging on the background image, and retain the authenticity of the close-up image.
Description
technical field [0001] The present invention relates to the technical field of image defogging, in particular to an image segmentation and defogging method and a terminal. Background technique [0002] At present, due to the existence of fog, haze or other particles in the outdoor environment, the gray value of the area covered by the fog in the captured image is high, the image is white, the outline of the scene is blurred, and the image feature extraction is difficult, which leads to image distortion and greatly affects the vision. As a result, it brings difficulties to real-time applications of outdoor work systems such as monitoring, intelligent navigation, and drone reconnaissance, and affects people's normal life. Restoring foggy images to obtain clear images is an urgent problem to be solved. Contents of the invention [0003] Embodiments of the present invention provide an image segmentation and defogging processing method and terminal, capable of segmenting an im...
