Results

Pre Opimization Post Opimization

• Calculated Homography and performed optimization using GTSAM factor graph techniques for creating a mosaic containing 200 underwater images.
• Extracted features and performed loop closures on overlapping images using factor graph for accurate image placement.
• Referenced and utilized the same dataset used in “O. Pizarro and H. Singh, "Toward large-area mosaicing for underwater scientific applications".
