Locally Oriented Anisotropic Image Diffusion: Application to Phenotyping of Seedlings

Abstract

A variant of the Perona-Malik anisotropic diffusion equation is introduced for the segmentation of multiple objects with crossings. The diffusion is automatically applied at the crossings locations along the main orientations of the objects. Application of this process is given for illustration on an original problem of plant imaging with the monitoring of the elongation of multiple crossing seedlings.
