Automated classification of three-dimensional reconstructions of coral reefs using convolutional neural networks
Fig 5
Sample texture-mapped and classified 3D reconstructions.
A) Texture-mapped and B) classified reconstructions of a segment of Little Grecian reef (LG1) viewed from overhead. C) Shows a side view of the classified reconstruction with shading to highlight its three-dimensional nature. D) Texture-mapped and E) classified reconstructions of a portion of Horseshoe reef (H1). F) Shows a side-view of the classified reconstruction. 3D reconstructions were generated and texture-mapped from the original images using commercial software (Agisoft Photoscan). The 3D reconstructions were then classified using the nViewNet-8 neural network. This figure is best viewed on a computer screen.
