- Image scaling algorithm performance evaluation measurements
- -----------------------------------------------------------
- Tested with Nokia Asha 311.
- 8 images scaled with the following relational sizes: 40 %, 50 %, 60 %, 70 %,
- 80 %, 140 %, 160 % and 200 %. The size of the original image was 220 x 272
- pixels, and bit depth 32.
