Digital Image Scaling
Ioannis Th. Andreadis, Angelos A. Amanatiadis · 2006
The proposed scaling algorithm outperforms other standard and widely used scaling techniques. The algorithm uses a mask of maximum four pixels and calculates the final luminosity of each pixel combining two factors; the difference in luminosity between the source pixels. The interpolation is capable of scaling both grey-scaling and color images of any resolution in any scaling factor. Its key characteristics and low complexity make the interpolation very fast and capable of standard tests are presented and compared to other scaling algorithms.
