Abstract
An image processing apparatus and method for restoring an image which is expected to be when there is no fog from a foggy image, the image processing method including: generating a pixel depth image of the foggy image by estimating a plurality of pixel depths of a plurality of pixels, respectively, included in the foggy image based on a channel difference between at least two of red (R), green (G), and blue (B) channels of the foggy image; processing the pixel depth image; obtaining an optical model parameter with respect to the foggy image; and restoring an image, which is expected to be when the foggy image does not include the fog, by using the processed pixel depth image and the optical model parameter.
Claims20
An image processing method comprising:
- generating a pixel depth image of a foggy image which includes fog therein by estimating a plurality of pixel depths of a plurality of pixels, respectively, included in the foggy image based on a channel difference between at least two of red (R), green (G), and blue (B) channels of the foggy image;
- processing the pixel depth image;
- obtaining an optical model parameter with respect to the foggy image;
- and
- restoring an image, which is expected to be when the foggy image does not include the fog, by using the processed pixel depth image and the optical model parameter.
An image processing apparatus comprising:
- a depth estimation unit which generates a pixel depth image of a foggy image which includes fog therein by estimating a plurality of pixel depths of a plurality of pixels, respectively, included in the foggy image based on a channel difference between at least two of red (R), green (G), and blue (B) channels of the foggy image;
- a refining unit which processes the pixel depth image;
- a parameter unit which obtains an optical model parameter with respect to the foggy image;
- and
- a restoration unit which restores an image, which is expected to be when the foggy image does not include the fog, by using the processed pixel depth image and the optical model parameter.
