  • Patent number: 11821991
    Abstract: Disclosed is in the present disclosure a dynamic compensation wind measurement lidar system, including a laser, an A/D converter, a signal processor, and a data processor. The signal processor includes a power spectrum calculation module, a motion sensor, and a pulse integration module. The pulse integration module divides an optical pulse transmitted in a single beam period into n sections for integration, where real-time motion and attitude data collected by the motion sensor is added to each of the sections for integration to improve a signal-to-noise ratio by integrating a power spectral density for a plurality of periodic pulse signals. In the present disclosure, by means of integrating optical pulses in single-beam dwell time by sections and attitude superimposing, an attitude compensation frequency may be greatly increased, and the attitude compensation frequency is adjustable.

  • Patent number: 8208692
    Abstract: A method for identifying a person using their finger-joint print including the outer skin around the proximal interphalangeal joint of a finger, the method comprising: capturing (10) an image of the finger-joint print of the person; extracting (12) a region of interest (ROI) based on a local convexity property of the finger-joint print; extracting (13) features representing the orientation of the lines in a finger-joint print image from the ROI using an extended Gabor phase coding scheme and the extracted features are represented in competitive code maps; wherein angular distance between the competitive code maps is compared (14) with a reference set in a database to identify the person.

  • Publication number: 20110317916
    Abstract: A method for spatial-temporal denoising and demosaicking for noisy color filter array (CFA) video, the method including applying spatial-temporal CFA video denoising (11) to the CFA video in order to generate a denoised CFA, applying initial color demosaicking (CDM) (19) to the denoised CFA video in order to generate a demosaicked video, and applying spatial-temporal post-processing (26) to the demosaicked video in order to reduce CDM artifacts and CDM errors and enhance the quality of the video.
