Automatically resizing demosaicked full-color images using edge-orientation maps formed in the demosaicking process. In a first example embodiment, a method for automatic upsampling of a demosaicked image includes several acts. First, a demosaicked image and an edge-orientation map that was created during the creation of the demosaicked image are received. Next, pixels of the demosaicked image are filled into an upsampled image. Then, edge-orientation values of pixels of the edge-orientation map are filled into an upsampled edge-orientation map. Next, an interpolation direction is determined for each pixel in which upsampling of the demosaicked image should be performed using the upsampled edge-orientation map. Finally, missing pixels in the upsampled image are estimated by performing interpolation along the interpolation direction using available pixels surrounding each missing pixel location.
