Fast Bitmap Images Resizing

Abstract

Image resizing is an important operation in digital image processing. In this paper, we introduce an image resizing scheme that produces significantly improved quality over the pixel replication method. This algorithm is suitable for real-time image resizing applications including: Virtual Reality, Optical Character Recognition, Symbol Recognition, and Car License Plate Recognition. Although this method produced “jaggies” at the edges in the resized image, the execution time is about 22 to 40 times fast than the Windows and the Weiman scheme, respectively.
