A second reference image combination unit generates a second combined reference block in which, by way of information required for generation of the combined reference block of the areas which have been coded, a second reference block and a predetermined area of the reference image used for the combination are identified and combined.
A video image encoding method including: a corresponding block specification step (S100) that specifies a corresponding block that corresponds to a target block; a reference image specification step (S112) that specifies, as a second reference image, an image belonging to a second viewpoint that corresponds to a first reference image that has been used to encode the corresponding block, when the target block and the corresponding block have the same time (S108); a predicted motion vector determination step (S110) that sets the motion vector of the corresponding block as the predicted motion vector; a motion vector determination step (S118) that determines the motion vector of the target block; a motion vector specification information generating step (S122) that generates motion vector specification information that specifies motion vectors; and encoding steps (S118, S124) that generate an encoding stream including encoding block and motion vector specification information.
Provided is a method involving: a step for generating a synthesized image corresponding to a target image on the basis of a first reference image and a second reference image; a step for generating side information indicating the virtual visual field at the position of the target image on the basis of the target image and/or the synthesized image; a step for generating a gradient strength image from the side information; a step for determining a gradient strength-based coefficient with regard to each pixel position in the gradient strength image, and for carrying out a modulo operation, in which a corresponding coefficient functions as a modulus, on the brightness value of each pixel position in the target image to generate a surplus image comprising the surplus of each pixel position calculated by means of the modulo operation; and a step for outputting the first reference image, the second reference image, and the surplus image as information expressing the target image, the first reference image, and the second reference image.
This image processing device includes a process of: acquiring first and second input images which correspond to an input image and which respectively have at least a first resolution and a second resolution higher than the first resolution; acquiring first and second reference images which correspond to a reference image and which have resolutions respectively corresponding to the first and second resolutions; through a search process between the first input image and the first reference image, calculating the amount of relative deviation of rotation and/or magnification between the first input image and the first reference image; correcting the first reference image on the basis of the amount of relative deviation, to thereby generate a first corrected reference image; through a search process between the first input image and the first corrected reference image, determining a corresponding location at the first resolution; and using by way of a reference a location in the second input image that is equivalent to the corresponding location at the first resolution, and utilizing the amount of relative deviation, performing a search process between the second input image and the second reference image, to thereby determine a corresponding position at the second resolution.
An image tracking apparatus is provided with an imaging apparatus, which picks up an image by an imaging optical system and generates image information; a setting section, which sets, based on the image information, first reference image information including image information that corresponds to a part of an image to be a target among the image information, and sets second reference image information based on information of an image in the vicinity of the image that corresponds to the first reference image information; and a recognizing section, which recognizes the target based on the first reference image information and the second reference image information.
In the index generation step: a first index indicating combinations including at least one reference image browsed by a first reference image, and a second index indicating combinations including at least one reference image browsed by a second reference image are set; the numbers for the at least one reference image included in the first index and the numbers for the at least one reference image included in the second index are scanned in a predetermined order; and a common index rearranged into a combination not containing the same reference image is generated.
This method involves: a step for generating a synthesized image corresponding to a target image on the basis of a first reference image and a second reference image; a step for generating a mask image indicating the potential error of the synthesized image with regard to the target image from the first reference image and the second reference image; a step for generating a residual image corresponding to the difference between the target image and the synthesized image; a step for generating a post-conversion image corresponding to the target image by allocating information of a region corresponding to the residual image to a region having a relatively large potential error on the basis of the mask image; and a step for outputting the first reference image, the second reference image, and the post-conversion image as information expressing the target image, the first reference image, and the second reference image.
Disclosed is an image encoding device provided with a prediction unit (2) which, in each macro-block, uses a pre-prepared fixed filter to generate a first reference image signal from a local decoded image signal stored in a memory (7), and uses a Wiener filter for integer pixels and a Wiener filter for generating non-integer pixels, with said filters being generated by a unit (6) for generating image quality improvement filters, to generate a second reference image signal from the local decoded image signal, then selects the most suitable reference image signal out of the first and second reference image signals and generates a prediction signal from the selected reference image signal and the separated image signal.
