摘要：A system and method for scaling images are provided. An upscaling algorithmor function is employed that increases the size of an image and then filters the upscaledimage to remove aliasing artifacts. The system and method provides for acquiring animage of a first size, detecting the geometry of the image, scaling the image to a secondsize, and filtering the scaled image with at least one filter based on the detectedgeometry. During the filtering process, the edges of objects in the upscaled image aredetected and different filter frequency responses are provided for the detected edges.Providing different filter frequency responses for the detected edges preserves moredetails for line images.
