Poisson Blending II

I re-wrote the Poisson Blending code using C++ and OpenCV. About the Algorithm, see my Previous Poisson Blending post. This time, I just used the most stupid way, just solving the Poisson Equation. You can improve it by using advanced methods. About solving discrete Poisson Equation using Jacobi, SOR, Conjugate Gradients, and FFT, read THIS.   In […]

Something About Convolution

I was in Communications Engineering major during my undergraduate years, I learnt Signals and Systems and Digital Signal Processing before, so I thought I was quite familiar with things like convolution, Fourier transform. However, recently I realized that what I knew is only sort of superficial things. I’m attending Prof. Eero Simoncelli‘s “Representation and Analysis of […]
