Abstract: A disease assessment method includes using a machine learning system and 2-D image data to quantify an extent of disease in the patient, wherein the machine learning system has been previously trained using 3-D image data for each of a plurality of 3-D images obtained from a plurality of subjects, and 2-D image data for each of a plurality of 2-D images obtained from the plurality of subjects, wherein each of the 2-D images is associated with a corresponding one of the 3-D images and is captured at the same time as the corresponding one of the 3-D images or within a certain predetermined time frame of capturing the corresponding one of the 3-D images, and wherein a ground truth for the 2-D images comprises for each of the 3-D images a quantification of an extent of the predetermined disease based on the 3-D image data for the 3-D image.

Abstract: There are disclosed methods to provide stable pose determinations of various three dimensional shapes. Methods are also disclosed for determining multiple, unique drawing descriptors for two dimensional drawings, and for obtaining intermediate three dimensional representations of two dimensional drawings as one way to determine the descriptor. Methods are also disclosed to provide for searching of two dimensional drawings and three dimensional shapes using user-defined input, which may be a drawing or sketch. User interactivity is provided to further refine search results.

Abstract: The invention discloses a search method of 3D model and device thereof. As stated in the invention, it transforms the query model and the object model into the set of 2D-slide polygons respectively; calculates the similarity between each 2D slice in the query model and the object mode by accumulating the similarities of all couples of 2D slices; and determines the search result according to the said total similarity. In accordance with the invention, it could be easily realize the search function of 3D model, and it is not sensitive to geometric noise, thus there's no need to look for the characteristic correspondence between models.

Abstract: There are disclosed methods to provide methods for beautifying sketches. Methods are disclosed for determining segments of drawings that represent geometric primitives and implied geometric constraints. Beautification methods provide for replacement of sketched primitives and over- and under-sketched drawings. After beautification methods provide for checking the initial segmentation of the sketch to determine whether false segmentation points were identified. Methods are also disclosed to provide for searching of drawings based upon a beautified sketch. User interactivity is provided to further refine search results.
