An image processing device includes processing circuitry configured to acquire a plurality of basis patterns for converting a first region and a second region in a target image, calculate a contribution ratio of each basis pattern, and select one or more basis patterns from higher contribution ratio to lower contribution ratio until a sum of contribution ratios of the selected one or more basis patterns reaches a specific first threshold. The processing circuitry is further configured to generate a control signal of an intensity that increases with a number of the one or more selected basis patterns, project a third region in the target image to the basis patterns to obtain a projection coefficient, reduce noise of the projection coefficient based on the intensity of the control signal, and reconstruct the third region using the projection coefficient after the noise is reduced. |
