Latest Patents
One of Ehn's latest patents is titled "System and method for image recognition using stream data." This invention provides methods and systems for identifying an individual by utilizing principal component analysis. It accounts for intra-individual variation by employing a plurality of images obtained from a stream of data. The system produces a compensated representation of the individual, which is then matched against a reference database to identify the individual accurately.
Another significant patent is "Systems and methods for forming a reduced-glare image." This method and system involve producing a reduced-glare image using at least two light sources positioned a selected distance apart. An image acquisition device captures two images of an object using illumination from each light source separately. The resulting images, which exhibit glare at different pixel locations, are combined to create a reduced-glare image.
