ABSTRACT:
A method and apparatus for interpolating image information obtains pixel information for a plurality of pixels surrounding a location of a pixel to be interpolated, whether the pixel is a missing pixel or an existing pixel whose color or intensity information is to be changed, and applies a gradient square tensor operation on a plurality of surrounding pixels to determine if the pixel to be interpolated is part of a geometric feature. If it is determined that the interpolated pixel is part of a geometric feature, such as a diagonal line or other suitable geometric feature, the method and apparatus uses pixel information from at least some of the surrounding pixels that are also determined to be the in geometric feature. This may be performed on a group of pixel basis and may include, for example, utilizing a block or kernel of pixels and a moving window of blocks of pixels to utilize the plurality of surrounding pixels.
