发帖数: 117 | 1 ICA, indepent component analysis is also a good
method for feature extracting.
I know a prof is doing 3d modeling using SVD,
he ask the students use ICA model to do the approach,
I feel that the method is computation expensive,
(I do not do this work, just have the sense).
Just read a short toturial paper, the preprocessing
is centering and whitening the data to be
zero mean and uncorrelated with unity covariance.
E(x) = 0;
cov(x) = diag.
consider a sequence of image, that will be a lot time to |
