Estimates the spatio-temporal Just Noticeable Difference profile of video frames!
This is a personal implementation of the paper "Spatio-Temporal Just Noticeable Distortion Profile for Grey Scale Image/Video in DCT Domain". If you use this code, you must cite the following paper:
Spatio-Temporal Just Noticeable Distortion Profile for Grey Scale Image/Video in DCT Domain", Zhenyu Wei and King N. Ngan, IEEE Transactions on Circuits and Systems for Video Technology, Vol.19, No.3, March 2009
This program requires a block-matching motion estimation algorithm to calculate the temporal JND profile. I have used the Adaptive Rood Pattern Search algorithm (The motionEstARPS function in line 136). You can download it from here. Other techniques would work as well.
Edit (Put in the video file location) and run demo.m to get started.
So,
Video file
T_JND_s = Spatial JND Profile
T_JND = Temporal JND Profile
