| Research Abstract |
In this research, to establish basic knowledge to extract and find application of useful information from outdoor scene image are aimed. The target objects are, for example, ships as moving artificial object and outdoor natural objects. The results can be categorized to ones on the sea and ones under sea. On the sea : To extract moving vector from ship image sequences, usually two assumptions are used : equi-brightness on the same point and smoothness. Instead of the later, local assumption of equi-movemerit is used and was successful. Extraction of moving ship from observed image sequence on moving ship has been attained on the inference of ego motion. Experiments to measure the direction of waves are performed, where edge detection of wave is used as basic technique. An approach to extract oil slick from the SAR image observed from satellite is performed. Under the sea : Reconstruction of sea ground structure from multiple side scan sonar images are investigated. After extracting common area within two images (oppositely observed), multi-stage matching to compensate possible distortion associated !by the observation. The result of the reconstruction of sea ground seems satisfactory. Others: Stereo I matching on plant image applying of increment coding matching is successful and some reconstruction result is convincing. In general, our aim is so far attained.
