Abstract
According to one embodiment, an image processing apparatus includes following units. The correlation calculation unit calculates correlations between a first region and predetermined first basis vectors. The distance calculation unit calculates distances between the first region and second regions on a subspace generated by the second basis vectors selected from the first basis vectors. The feature quantity calculation unit calculates a feature quantity based on the correlations. The weight calculation unit calculates weights based on the distances and the feature quantity. The pixel value calculation unit calculates a weighted average of pixel values according to the weights to generate an output pixel value.
