Abstract: An example of a non-transitory computer-readable medium storing machine-readable instructions. The instructions may cause the processor to receive a three-dimensional (3D) object representation and subdivide it into a triangular grid. Curved triangles may be calculated for triangles in the triangular grid. The triangles may be subdivided and differences calculated between corresponding sections of the curved triangles and the received 3D object representation.

Abstract: According to examples, an apparatus may include a processor and a non-transitory computer readable medium on which is stored instructions that may cause the processor to create a 2D reference mesh for an image of a curved visual mark, establish correspondences between finder pattern points in the curved visual mark and points of the 2D reference mesh, and determine a curved 3D mesh having a radius that results in a minimal reprojection error of a projective transform estimated for correspondences between the 2D reference mesh and the curved 3D mesh while the radius remains below a predefined upper limit. The instructions may also cause the processor to sample components of the curved visual mark in elements of the determined curved 3D mesh to form a 2D planar image of the curved visual mark and analyze the 2D planar image of the curved visual mark to read the curved visual mark.

Abstract: The present invention provides fluorescent nanoparticle composites themselves, the process of preparing such composites, to systems for rapid diagnosis (as “kits”) containing such composites, and to the use of such composites. In a preferential embodiment, the composites of the present invention have an affinity for biological molecules, such as DNA. The present invention also comprises the preparation of probes containing biological material, upon which are added fluorescent nanoparticle composites, making viable a rapid and economic biological diagnosis of, for example, diseases and genetic traits, notably in the medical and veterinarian fields.
