| 1 | For every two consecutive video frames I1,I2 do |
| 2 | D(x,y,t)=I1(x,y,t)-I2(x,y,t-1) |
| 3 | A(x,y,t)=D(x,y,t) \\ with enhanced Local Motion as mentioned in Algorithm 1. |
| 4 | F(v,w,t)=FT(A(x,y,t)) \\ FT denotes 2D fourier transform. |
| 5 | Apply Radon transform, R(d,θ)=Radon(f(v,w,t)) |
| 6 | Normalize, P(θ)=max(R(d,θ)) |
| 7 | K=Kurtosis(R(d,θ)) |
| 8 | M=Mean(R(d,θ)) |
| 9 | EndFor |
| 10 | Return Histogram(P, nbins), Histogram(K,nbins), Histogram(M,nbins). |
