EE381K Multidimensional Digital Signal Processing - M-D DCT
Lecture by Prof. Brian L. Evans
- Homework #4 is due Tuesday, February 26th.
- Quality factor (QF) has range 1-100.
Higher QF means less quantization and hence a lower compression ratio.
"For good-quality, full-color source images, the default IJG quality
setting (Q 75) is very often the best choice. This setting is about
the lowest you can go without expecting to see defects in a typical image."
