Enabling Visual Understanding of Underwater ScenesProf. A.N. Rajagopalan, IPCV Lab, Indian Institute of Technology MadrasUnderwater scene understanding from visual data poses many challenges due to loss of contrast, low light, haziness, and color distortion in the captured images. Recovering a clean image and the corresponding 3D depth map from underwater observations is fundamental to high-level tasks involving scene understanding. Towards this end, we have devised a learning methodology that effectively utilizes both haze and geometry by harnessing the physical model for underwater image formation in conjunction with view-synthesis constraint. The proposed method is completely self supervised and simultaneously outputs the depth map and the restored image in real-time (55 fps). To facilitate self-supervision, we collected a Dataset of Real-world Underwater Videos of Artifacts (DRUVA) in shallow sea waters. DRUVA is the first UW video dataset that contains video sequences of 20 different submerged artifacts with almost full azimuthal coverage of each artifact. The proposed approach, the dataset DRUVA, and results and comparisons will be discussed along with recent developments. |
