2. Recap:Main tasks in image processing
Mathematical technique for imaging (in 1 sentence):
TRANSFORM an input image to a better image
Mathematically,
can be LINEAR:
can be NON-LINEAR

3. Recap: some mathematics!
You have learnt from Supplementary note 1:
How linear operator to transform an image (to a better image) is defined? (PSF)
Shift invariant v.s. convolution
Separable operator v.s 1D transformation
