Latest Patents

One of his latest patents is titled "Three-dimensional calibration using orientation and position sensitive calibration pattern." This patent discloses systems and methods that utilize an orientation/position-sensitive calibration pattern for the three-dimensional calibration of imaging systems. The method involves positioning the pattern on a support, capturing images with calibrated cameras, and determining coordinate pairs of corresponding points in the image and the pattern. This process optimizes the calibration of each camera's position, orientation, zoom, and lens distortion, ultimately constructing a three-dimensional camera calibration model. Another significant patent is "Automatic operator-induced artifact detection in document images." This patent describes techniques for scanning documents where artifacts, such as a hand or body part, are automatically detected in the scanned image. If an artifact is found in a critical portion of the image, a signal is issued to re-scan the image, ensuring high-quality results.
