According to an embodiment, an image processing apparatus includes a feature data calculator, a generating unit, and an adding unit. The feature data calculator calculates feature data representing changes in pixel values within a first range of an input image. The generating unit obtains a weight of a predetermined image pattern on the basis of a probability distribution and the feature data. The weight represents a pattern of changes in the pixel values. The probability distribution represents a distribution of relative values of feature data of a learning image containing a high-frequency component with respect to feature data of a learning image. The generating unit weights the predetermined image pattern with the weight so as to generate a high-frequency component with respect to the input image. The adding unit adds the high-frequency component to the input image.

According to one embodiment, an image processing apparatus includes an acquisition unit, a clustering unit, a detection unit, and a correction unit. The acquisition unit is configured to acquire a moving image including a plurality of frames. The clustering unit is configured to cluster frames having a similar scene to the same group in the moving image. The detection unit is configured to detect at least one object region from each frame clustered to the same group, and to calculate a color distribution of the object region of the each frame. The correction unit is configured to select a typical color distribution of the object region from the color distribution of the each frame, and to correct a color of the each frame clustered to the same group, based on the typical color distribution.

According to an embodiment, an image processing apparatus includes a generation unit. The generation unit generates a texture image by searching for a similar pixel area to a processed pixel area near a processing target pixel in the texture image from a neighboring area at a position corresponding to the processing target pixel in a sample texture image and assigning the processing target pixel a pixel value near the similar pixel area in accordance with a positional relationship between the processed pixel area and the processing target pixel. The generation unit searches for the similar pixel area based on a similarity between a pixel value in a pixel area in the neighboring area and a pixel value in the processed pixel area and a determination result indicating whether each pixel in the neighboring area expresses a same object as that expressed by the processing target pixel.

An image processing device includes an acquisition unit, a memory, a search unit, and a synthesis unit. The acquisition unit acquires a moving image including a plurality of images, and sets a pixel in a process image as a target pixel. The process image is to be processed in the moving image. The memory stores a fine texture image obtained by extracting a texture component in a reference image different from the process image. The search unit sets a pixel position of the target pixel as a first position, and to search a predetermined range in the fine texture image in order to find a second position corresponding to the first position. The synthesis unit synthesizes a pixel value of the second position in the fine texture image with a pixel value of the target pixel.
