Method and apparatus for processing image

An apparatus for processing an image, the apparatus comprising:

• at least one processor;
• and
• a memory storing instructions, wherein the instructions, when executed by the at least one processor, cause the at least one processor to perform operations, the operations comprising:
• acquiring a to-be-processed foggy image, and performing minimum value filtering on the to-be-processed foggy image to obtain a grayscale image of the to-be-processed foggy image;
• selecting, in a descending order pixel values, a target number of pixel points from the grayscale image, and determining an image area corresponding to the selected pixel points from the to-be-processed foggy image;
• acquiring pixel values of the pixel points included in the image area, and determining an atmospheric light value based on the acquired pixel values;
• and
• performing image defogging processing on the to-be-processed foggy image based on the grayscale image and the atmospheric light value to obtain a processed image.

A non-transitory computer readable medium, storing a computer program thereon, the program, when executed by a processor, causes the processor to perform operations, the operations comprising:

• acquiring a to-be-processed foggy image, and performing minimum value filtering on the to-be-processed foggy image to obtain a grayscale image of the to-be-processed foggy image;
• selecting, in a descending order of pixel values, a target number of pixel points from the grayscale image, and determining an image area corresponding to the selected pixel points from the to-be-processed foggy image;
• acquiring pixel values of the pixel points included in the image area, and determining an atmospheric light value based on the acquired pixel values;
• and
• performing image defogging processing on the to-be-processed foggy image based on the grayscale image and the atmospheric light value to obtain a processed image.
