20150063719 | IMAGE PROCESSING APPARATUS FOR REMOVING HAZE CONTAINED IN STILL IMAGE AND METHOD THEREOF - An image processing apparatus for removing haze from an image includes a haze brightness measurer, a transmission estimator and an image reconstructor. The haze brightness measurer is configured to measure haze brightness in the image. The transmission estimator is configured to estimate a blockwise transmission based on a final cost function value calculated by a contrast and an image loss of the image, and to estimate a pixelwise transmission by using the blockwise transmission. The image reconstructor is configured to generate a reconstructed image by using the haze brightness and the pixelwise transmission. | 03-05-2015 |
20150071563 | IMAGE-PROCESSING APPARATUS FOR REMOVING HAZE CONTAINED IN VIDEO, AND METHOD THEREFOF - An image processing apparatus includes a haze brightness measurer to measure haze brightness in an image containing haze, a transmission estimator to estimate a blockwise transmission for generating a least final cost function value that is calculated by using a contrast, an image loss and a time loss of the image and to estimate a pixelwise transmission based on the estimated blockwise transmission, and an image reconstructor to reconstruct the image by using the measured haze brightness and the estimated pixelwise transmission. | 03-12-2015 |
