  • Publication number: 20210142445
    Abstract: An artificial intelligence (AI) decoding apparatus obtains image data corresponding to a first image, which is AI-downscaled from an original image by an AI encoding apparatus by using a first deep neural network (DNN); reconstructs a second image corresponding to the first image, based on the image data; and obtain a third image, which is AI-upscaled from the second image, convolution is performed based on the second image and second parameters of a filter kernel included in a second DNN, wherein each of the second parameters is an integer value, and the second parameters are determined as values associated with first parameters of a filter kernel included in the first DNN. Embodiments use memory-efficient values with respect to filter kernels. Parameters used to obtain the memory-efficient integer values may be obtained via joint training between the first DNN and the second DNN.

  • Patent number: 9336577
    Abstract: 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.
