Q1) [40 points) Three-Frame Differencing (TFD), when applied real-time, performs an AND operation between two images, one of which comes from frame differencing between It) and I(t-k), and the other is frame differencing between l(-k) and I(t-2k). Write a pseudo-code for the TFD algorithm, similar to the ones we saw in class. Q2) (20+40 - 60 points) Motion History Image (MHI) technique uses a frame differencing inside to generate M(t). In its original form SFD is used. Instead of SFD, we can use a) ABS, b) TFD. Write pseudo-code for each case separately
