Abstract

This is a constrained optimization type of numerical algorithm for removing noise from images. The L1-norm of total variation of the image is minimized subject to constraints involving the statistics of the noise. The constraints are imposed using Lagrange multipliers. The solution is obtained using the gradient-projection method. This amounts to solving a… (More)
