Image scaling using vector planes and directional information
Hwasup Lim, Young Ho Lee, Seongjoon Yang · 2005
We propose a novel image scaling algorithm utilized in HDTV and other digital image appliances. Vector planes and directional information are employed to interpolate data in an image modeled as a three dimensional surface. This technique provides fast image scaling that generates natural looking images and preserves edges while avoiding jagging and ringing effects - common artifacts from image enlargement.
