Abstract:
A method for encoding a plurality of input images containing mutually related information is provided. The method includes the steps of estimating a motion image indicating a change component from one or more previous input images, contained in a subsequent input image, generating a residual image from a difference between the subsequent input image and the estimated motion image, specifying a region whose pixel value should be defined by a remainder among pixels constituting the residual image, based on the pixel value of the residual image, converting, into a remainder, the pixel value for the specified region which should be defined by a remainder, and encoding the residual image after the conversion and additional information specifying the region which should be defined by a remainder.
Abstract:
Provided is a method for reducing data size of a plurality of images containing mutually similar information. The present method includes the steps of: generating a synthesized image corresponding to a target image based on a first reference image and a second reference image; generating a mask image indicating a potential error of the synthesized image with respect to the target image from the first reference image and the second reference image; generating a residual image in accordance with a difference between the target image and the synthesized image; generating a converted image corresponding to the target image by assigning, based on the mask image, a region where the potential error is relatively large, information on a corresponding region of the residual image; and outputting the first reference image, the second reference image and the converted image as information representing the target image, the first reference image and the second reference image.
Abstract:
A method for encoding a plurality of input images is provided. The method includes the steps of generating a first residual image from a difference between a first input image and a corresponding first predicted image, converting, into a remainder, a pixel value included in a region of the first residual image which should be defined by a remainder, generating a second residual image from a difference between a second input image and a corresponding second predicted image, converting, into a remainder, the pixel value included in a region of the second residual image which should be defined by a remainder, and coding the first residual image after the conversion, the second residual image after the conversion, and additional information specifying the region which should be defined by a remainder in each of the first residual image and the second residual image.
Abstract:
Provided is a method including the steps of: generating a synthesized image corresponding to a target image based on a first reference image and a second reference image; generating side information which is information on a virtual view at a location of the target image, based on at least one of the target image and the synthesized image; generating a gradient image based on the side information; determining a factor in accordance with a gradient for each pixel location of the gradient image, and performing a modulo operation using, as a modulus, a factor corresponding to an intensity value at each pixel location of the target image, to generate a remainder image composed of remainders of respective pixel locations calculated by the modulo operation; and outputting the first reference image, the second reference image and the remainder image as information representing the target image, the first reference image and the second reference image.
