Triangulation Method And Morphological Operations For Measurements Of Underwater Objects Using Stereo Vision

This thesis improves the accuracy in detection and range estimation of any objects underwater by using stereo vision. Nowadays there are two major types of camera produced by the industry with the purposes of capturing underwater image or video. One is with built in waterproof camera while the other...
