Comparison of 3d coral photogrammetry (cp) and coral video transect (cvt) for coral lifeform analysis using low cost underwater action camera

This study evaluated the use of 3D Coral Photogrammetry (CP) and Coral Video Transect (CVT) images obtained from SCUBA divers for coral lifeform analysis using low- cost underwater action camera. Comparison were made between the datasets obtained from both methods on nine (9) transect within 4m x 7m...
