How to obtain a SURE by monte carlo algorithm for license plate?

Robust Blur Kernel Estimation for License Plate Images from Fast Moving Vehicles. The above is the IEEE project, which I am trying to implement. In that I am in need to estimate the angle. Could anyone help with the code or idea?

What is "SURE" in this context?

Steins unbiased risk estimate (SURE)

Can you give the matlab code for the following algorithm?

Input: Blurred image B, step Δ, initial angle θ0, a moderate
length l, k = 0
1: while not converged do
2: Generate uniform linear kernel kl,θk , kl,θk−Δ, kl,θk+Δ
3: Solve Eq. (5) with kernels kl,θk , kl,θk−Δ, kl,θk+Δ, get
deblurred images Il,θk , Il,θk−Δ, Il,θk+Δ
4: Solve Eq. (6) with Il,θk , Il,θk−Δ, Il,θk+Δ, get Al,θk ,
Al,θk−Δ, Al,θk+Δ
5: if Al,θk == min(Al,θk ,Al,θk−Δ,Al,θk+Δ)
6: converged and return
7: elseifAl,θk−Δ == min(Al,θk ,Al,θk−Δ,Al,θk+Δ)
8: θk ← θk − Δ
9: else
10: θk ← θk + Δ
11: end while
Output: θk

X = argmin I {|I|TV + λ 2 kθ ∗ I − B|2 F } (5) min αi Σ |αi s.t. ΩiX = Dαi (6)

No I do not have code for that.
