The filter,which combines the properties of Gaussian filter and Gradient Inverse Weighting Filter,takes simultaneously the space distance and pixel distance into account,so as to choose the pixels and their weights for local smoothing.

In view of deficiencies of Canny algorithm in processing range image of light detection and ranging,such as generating many false edges,losing weak edges and lacking objectivity in threshold determination,an adaptive method is proposed in this paper.

The research presented in this paper is focused on segmentation of range image captured by vehicle-borne laser scanning systems.

3 D vision information based on range image can be used to accomplish obstacle detection and terrain analysis efficiently.

Method for 3-D objects recognition base on phase-encoded range images;

One of the most important contents about coherent imaging laser radar range image processing is suppressing the background.

In the radar system that can obtain one dimensional range image of the target by using STRECTH pulse compression,all kinds of system errors lead to the increase of the side lobe level and broadening of the main lobe,thus degrading the image.

A hierarchical filtering algorithm for processing distance images;

The distance images and intensity images can be given by the software.

The range image is abstracted from the original data and then the height texture is used for assisting classification.
