Abstract
In an aspect of an image processing technique according to the present invention, a high-frequency component is extracted from a low-resolution image z which is a restoration target, and a high-frequency image z' is generated (#). Interpolation filter coefficients A′, B′and πand a representative high-frequency image z′are set (#), a Gaussian mixture model represented by x=Σ{((A′×z′)+B′)×w((z′−z′), π)} is assumed and a filtering process is applied to the high-frequency image z′ (#). On the other hand, an enlargement process is applied to a low-frequency component and a medium-frequency component of the low-resolution image z (#), a processing result of the filtering process and a processing result of the enlargement process are added (#), and a high-resolution image is restored.
