Abstract
A method for resizing an input digital image having input pixel values to produce an output digital image having output pixel values, wherein the output digital image has a lower resolution and wherein single pixel width details in the input digital image are preserved, the method being performed by a processor and comprising: determining an output pixel value for the output digital image by interpolating within a corresponding neighborhood of image pixels in the input digital image; detecting whether the input digital image contains a fine detail within the corresponding neighborhood of image pixels; adjusting the output pixel value when a fine detail is detected; and repeating steps a)-c) for a plurality of output pixels.
