Abstract: An apparatus for expanding a source pixel in a digital image includes an edge direction detector detecting edge direction in the vicinity of the source pixel. An interpolator interpolates multiple sets of pixels in a region surrounding the source pixel in the detected edge direction to generate a set of output pixels representing an expansion of the source pixel. Methods and computer programs for expanding a source pixel in a digital image are also provided.

Abstract: A method of generating a high-resolution image from a set of source low-resolution images includes estimating a high-resolution image based on the set of source low-resolution images. The estimated high-resolution image is then transformed into a set of estimated low-resolution images. The set of source low-resolution images is compared with the set of estimated low-resolution images to generate a set of low-resolution errors. The set of low-resolution errors is transfomed into a set of high-resolution errors. A high-resolution error image based on the set of high-resolution errors is generated. The high-resolution error image is combined with the estimated high resolution image to yield an updated estimated high-resolution. The above steps are repeated until the updated estimated high-resolution image is of a desired quality.

Abstract: A system and method of creating a panorama image from a series of source images includes registering adjoining pairs of images in the series based on common features within the adjoining pairs of images. A transform between each adjoining pair of images is estimated using the common features. Each image is projected onto a designated image in the series using the estimated transforms associated with the image and with images between the image in question and the designated image. Overlapping portions of the projected images are blended to form the panorama image.

Abstract: A system and method of editing a digital image to remove an unwanted object includes designating a rectangular region of the digital image including a subset of pixels within the digital image that includes the object to be removed. A band of pixels adjacent one major side of the rectangular region is selected and a mirror of the selected band of pixels is copied in a repeating pattern to define a first matrix corresponding in size to the designated region. A band of pixels adjacent the opposite major side of the rectangular region is then selected and a mirror of the selected band of pixels is copied in a repeating pattern to define a second pixel matrix corresponding in size to the designated region. The pixels of the first and second matrices are blended according to a first blending equation to create an initial texture.
