Nov14. Mesh Smoothing

Mesh smoothing: local averaging minimize local gradient energy in 3 dimensions Fourier transform (low pass filter) similar to local averaging idea image convolution F(A*B) = F(A) * F(B) Spectral Analysis In general: extending eigenvalues, eigenvectors to linear operators on (continuous) functions. Fourior transform: approximate signal as weighted sum (linear combination) of sines and cosines of … Read moreNov14. Mesh Smoothing
