  • Patent number: 10099400
    Abstract: A method and system for detecting and controlling the quality of debarking at the surface of a wooden log provide information on main parameters related to the debarking quality of the log surface, including fiber loss and residual bark. The debarking quality detecting method and system involve measurement of three-dimensional profile of at least a portion of the log surface to generate corresponding profile image data, which is processed to generate data indicative of the texture of the log surface. The texture data is then analyzed to generate resulting data on the debarking quality parameters. That quality indicative information can be generated on a continuous basis to provide an objective assessment of the quality performance in real-time in view of target productivity, and may then be used to perform optimal adjustments of the debarker operating parameters, either manually by the operator or automatically through feedback control.

  • Patent number: 9578312
    Abstract: A method of integrating binocular stereo video scenes with maintaining time consistency includes: propagating and extracting a contour of moving object of stereo video A; integrating and deformating of parallax between moving object and dynamic scene with time consistency; color blending of moving object and dynamic scene with time consistency where a method of median coordinate fusion is utilized. The method is simple and effective to utilize a small quantity of user interactions to successfully extract moving objects from stereo video which are same in time and as consistent as possible between left view and right view to develop multiple constraint conditions to guide the integration and deformation of parallax of moving object and dynamic scene and allow moving object to conform to the rules of perspective of dynamic scene. Moreover, the deformation result of moving object is smooth and consistent and can avoid effectively the occurrence of “dithering” phenomenon.

  • Patent number: 9105053
    Abstract: An approach is provided for determining a user age range. An age estimator causes, at least in part, acquisition of voice data. Next, the age estimator calculates a first set of probability values, wherein each of the probability values represents a probability that the voice data is in a respective one of a plurality of predefined age ranges, and the predefined age ranges are segments of a lifespan. Then, the age estimator derives a second set of probability values by applying a correlation matrix to the first set of probability values, wherein the correlation matrix associates the first set of probability values with probabilities of the voice data matching individual ages over the lifespan. Then, the age estimator, for each of the predefined age ranges, calculates a sum of the probabilities in the second set of probability values corresponding to the individual ages within the respective predefined age ranges.
