thanks mate. this is absolutely brilliant stuff. part of the confusion with learning about this stuff is that people either teach a transform in isolation, or they dont describe the actual benefit+difference of one transform versus another. this is really grounded stuff and you've made it practical. you sir deserve a slice of cheese cake. and a scone.
this guy is the difference between going to a good school to get education vs trying to learn it by yourself because your teacher does not know how to relate material to you. Good job Doc
Is it correct to summarize that DCT is useful over DFT because the DCT is real only, the compression is approximately half the space needed of a DFT which is both real and imaginary?
This is a widely used argument. But you can combine two real images of the same format as real and imaginary part of ONE complex-valued image. Then apply the FFT2 and then decompose the resulting parts...

Excelente, Explicacion clara, sencilla y ordenada. Saludos de Argentina.
Error at 1:48. LTI changes Amplitude AND PHASE, and leave frequency unchanged.
??? the fundamental frequency is not been modified there.
Great explanation !
