Multiple view reconstruction

The first video describes the series of image analysis processes undertaken to produce 3D plant canopy models.

Though the process as a whole is complex, each sub-task is some varation on topics and ideas covered in this course, including:

• 3D reconstruction via multiview correspondence to make a point cloud
• Noise removal – in this case point filtering
• Segmentation – clustering of points into patches of approximately flat leaf
• Combination of ideas from region growing and snakes – level set method

The resulting 3D reconstructions are surfaces, suitable for modelling light reflection and photosynthesis.
