Overview

Segmenting regions of interest in images is a wide field in Computer Vision and Image Processing. Some methods include a kind of pre-segmentation inside but there are some which can be boosted using masks on the image or masked images. In this package we provide ROS nodes to help with this image processing step. disparity_k.jpg histogram_segmentation_orange_ball_k.png

ROS API

disparity_segmentation

Provides distance-based segmentation based on a disparity image computed using stereo cameras.
