We analyse the convergence of the proximal gradient algorithm for convex composite problems in the presence of gradient and proximal computational inaccuracies.

Image-Guided Depth Upsampling via Hessian and TV Priors

no code implementations • 31 Oct 2019 • Alireza Ahrabian, Joao F. C. Mota, Andrew M. Wallace

We propose a method that combines sparse depth (LiDAR) measurements with an intensity image and to produce a dense high-resolution depth image.
