Abstract: A system for plant leaf identification includes: a plant image capturing unit which captures an image of a target plant to generate a plant image; a plant area image extraction unit which separates a background area and a plant area in the plant image to generate a plant area image including the plant area; a plant area image skeletonization unit which skeletonizes the plant area image to generate a skeletonized plant area image; a candidate leaf path generation unit which identifies a root vertex, a junction vertex and a leaf tip vertex in the skeletonized plant area image, and generates a plurality of candidate leaf paths by calculating all possible paths from the root vertex to the leaf tip vertex; and a final leaf path reconstruction unit which reconstructs a final leaf path matching the plant image by selecting the plurality of candidate leaf paths.

Abstract: The virtual model control system has an input device configured to provide input information for formation, movement or transformation of a virtual model; a control device configured to form the virtual model based on the input information received from the input device, move or transform the virtual model, form a plurality of physical particles at the virtual model, form contact point information therefor, and move the plurality of physical particles to update the contact point information; an output device configured to output the virtual model to the outside. When the plurality of physical particles penetrates into another virtual model in the virtual space, the control devices update the contact point information so that the penetrating physical particles are rearranged at an outer side of the another virtual model.
