  • Patent number: 11818479
    Abstract: A technique is presented for quantizing pixels of an image using Sigma Delta quantization. In one aspect, pixel values for an image are segmented into columns of pixel values; and for each column in the matrix, pixel values of a given column are quantized using sigma delta modulation. The pixel values in a given column are preferably quantized as a whole, thereby minimizing accumulated quantization error from a starting pixel value in the given column to a current pixel value in the given column. In another aspect, the pixels of an image are quantized using a 2D generalization of Sigma Delta modulation.

  • Patent number: 10452195
    Abstract: An electronic system includes a display interface configured to display a calibration point; a sensor, coupled to the display interface, and configured to capture a first gesture directed at the calibration point from a first position; capture a second gesture directed at the calibration point from a second position, wherein the second position is different from the first position; and a control unit, coupled to the display interface, and configured to display a position indicator on the display interface based on a directive gesture captured by the sensor, the first gesture, and the second gesture.

  • Patent number: 7508373
    Abstract: An input method and apparatus is provided for use in various computer and mobile devices. The input device utilizes a rotating dial in which four arrows printed on the dial are rotated to select characters that are fixed along the circumference of a circle. The characters are divided into various zones. The zones are utilized to encode various letters and numbers. Additionally the zones may be utilized for editing and control functions. The dial may be freely rotated. Pressing any arrow inputs the character that the arrow points to on the dial. The input device and method may encode Asian language characters according to a set of encoding rules.

  • Patent number: 7505606
    Abstract: Embodiments of the invention determine whether an image has been altered. Sets of patches are selected in the image, and corresponding inverse response functions are provided to a support vector machine (SVM). The support vector machine is trained with exemplary normal and abnormal inverse response functions. Once trained, the support vector machine analyzes inverse response functions corresponding to a suspected image. The support vector machine determines if the inverse response functions are normal or abnormal by analyzing a set of features. In one embodiment, features include measures for monotonic characteristics, fluctuation characteristics, and divergence characteristics of the red, green, and blue components of a tuple. Each tuple of inverse response functions is associated with a set of patches selected in the image.
