Abstract

Image filtering by Richardson-Lucy algorithm shows an iterative solution for monodimensional signal deconvolution. In this paper the performance of this algorithm will be verified when lidar (light detection and ranging) signals are pre-filtered by an adaptive low-pass filter followed by a couple of ner/nerd filters. Most interesting results, for real-time deconvolution and filtering of lidar signal, will be also showed.
