For video scaling part, the polyphase filter design give more details on FIR filter design for fractional ratio. However, other methods like spline interpolation or nearest neighboring pixel method is not described here. The nonlinear scaling method gives more or less hints to design them which are all based on the high order polynomials and related to warping theory.

For digial video warping, it is better to refer to Dr. George Wolberg's book "Digital Image Warping" as keystone correction implementation

This book gives some information regarding gardient
calculations on edge detection which are based on frame level of video sequence. The de-interlacing parts did not give more industry designs on motion adaptive algorithms which use multiple fields data for motion detection/motion history and motion compensation based methods.

The diagonal direction based deinterlacing is not described here such as simple ELA algorithm.

The polyphase filter based deinterlacer will not work on fast motion video sequences when intra-field interpolation should be used. For slow motion of video, it might be ok to use vertical temporal filtering or even the previous field pixel for almost static image to create good result as intra field interpolation.

Readers who want to learn motion compensation based deitnerlacing should refer to Dr. Erwin Bellers's book "De-interlacing" for more advanced algorithms such as majority selection on 3D recursive search block matcher.

The 3:2 reverse pulldown for film material part only describes
pixel differences method. Block based variance or deviation methods are not mentioned here.
