Patent number: 9734384Abstract: The present invention describes a method and the system for matching fingerprint images obtained from different fingerprint image capturing devices and implemented in an electronic device. Specifically, the method has steps of identifying minutiae and then identifying core point of the fingerprint images. Thereafter, a line of symmetry is determined and minutiae are identified by matching ridge count, location angle and orientation angle of a first image of the fingerprint images with a second image of the fingerprint images is identified. Thereafter, prominent minutiae from the candidate minutiae having three adjacent minutiae with same local structure are identified.

Patent number: 9734576Abstract: After selecting two or more image series for comparison, images of the image series are interleaved so that they are alternatively displayed in a comparison pane on a display device. In one embodiment, after one or more image series are selected for comparison, an interleaved image series is created containing each of the images of the one or more selected image series, or, alternatively, the interleaved image series comprises links to the images arranged in the interleaved pattern. If differences exist in the images of the multiple image series, these differences may be more easily detectable as the display device cycles between the images. Comparison of images in an interleaved image series may be more advantageous if the images of each selected image series are of a common anatomical area, common image size, and the images are in the same order.Type: GrantFiled: September 1, 2016Date of Patent: August 15, 2017Assignee: D.R.

Patent number: 9728012Abstract: An object-image alignment data generating method for use in an object recognition system is presented. The method obtains a 3D model and a set of 2D images of the object. Each 2D image from the set is captured based on a particular camera point of view. The method then uses the 3D model of the object to generate multiple silhouettes of the object according to different camera point of views. Each silhouette is then matched and aligned with a 2D image based on the corresponding camera point of view. The method also derives at least one descriptor from the 2D images and compiles feature points that correspond to the descriptors. Each feature point includes a 2D location and a 3D location. The method then generates an object-image alignment packet by packaging the 2D images, the descriptors, and the feature points.Type: GrantFiled: October 4, 2016Date of Patent: August 8, 2017Assignee: Nant Holdings IP, LLCInventor: Matheen Siddiqui

Patent number: 9712828Abstract: Technologies are generally described to identify foreground motion detection in compressed video data. In some examples, a foreground motion detection module may determine transform-coefficient-magnitude sums and motion-vector-magnitude sums associated with block coding units (BCUs) in compressed video data without decompressing the video data. The foreground motion detection module may also determine a background mean and a background co-variance associated with the compressed video data. To determine whether the BCU(s) contain foreground motion, the foreground motion detection module may determine a statistic based on the transform-coefficient-magnitude sums, the motion-vector magnitude sums, the background mean, and the background co-variance and compare the statistic to a threshold.Type: GrantFiled: July 23, 2015Date of Patent: July 18, 2017Assignee: INDIAN STATISTICAL INSTITUTEInventors: Bhaskar Dey, Malay Kumar Kundu
