Method for Denoising Time-of-Flight Range Images

摘要

A method for denoising a range image acquired by a time-of-flight (ToF) camera by first determining locations of edges, and a confidence value of each pixel, and based on the locations of the edges, determining geodesic distances of neighboring pixels. Based on the confidence values, reliabilities of the neighboring pixels are determined and scene dependent noise is reduced using a filter.

1. A method for denoising an image, wherein the image is a time-of-flight (ToF) range image of pixels, comprising steps of:
determining locations of edges, and a confidence value of each pixel; determining, based on the locations of the edges, geodesic distances of neighboring pixels; determining, based on the confidence values, reliabilities of the neighboring pixels; and reducing scene dependent noise using a filter, wherein the ToF range image is acquired by a ToF range camera, and the steps are performed in a processor.
