摘要： The present invention provides an image quality improvement processing apparatus that removes occlusion regions and regions that the registration error is large, selects pixels suitable for the image quality improvement processing, and generates an image with high image quality.The image quality improvement processing apparatus of the present invention comprises a means that performs the registration processing between a basis image and an input image and generates a basis image that registration processing is already performed, a means that selects pixels used in an image quality improvement processing based on the basis image that registration processing is already performed and the input image by a predetermined condition and generates an input image that pixel selection is performed by performing an image synthesis based on a pixel selection result and the input image, a means that amends pixel values of the input image that pixel selection is performed so that luminances of pixels of the input image that pixel selection is performed become equal to luminances of corresponding pixels of the basis image that registration processing is already performed and generates an input image that pixel selection and luminance amendment are performed, and a means that performs the image quality improvement processing based on the input image that pixel selection and luminance amendment are performed and generates the image with high image quality.

摘要： The present invention provides a region-selection-based image registration method for estimating motions between an image of interest in an image sequence and a reference image in the image sequence which can be applied to the registration of the object having every geometry and by which the high-precision image registration with robustness to illumination variation and occlusion can be conducted.An image registration method for conducting a high-precision image registration between a reference image in an image sequence capturing an object and an image of interest in said image sequence, the method characterized in that a predetermined region on the reference image is set as a region of interest, when conducting the high-precision image registration, a motion parameter is estimated based on pixels of a mask image representing a region where the registration is performed precisely by a predetermined transformation within the region of interest that is set. The mask image is generated by utilizing the similarity evaluation between images.
