  • Patent number: 9792866
    Abstract: Methods for detecting and eliminating a ghosting effect of liquid crystal display (LCD) are disclosed. The ghosting effect detecting method comprises the steps of providing a visual persistency period, providing a maximum color alternation speed of the LCD, obtaining a threshold value by multiplying the human visual persistency period by the maximum color alternation speed, calculating a variation of an intensity level of each of the plurality of pixel components of the LCD and comparing the threshold value and the variation of the intensity level to obtain a comparison result to determine whether the ghosting effect exists in the pixel component.

  • Publication number: 20120147014
    Abstract: Disclosed is a method for automatically extracting personal styles from captured motion data. The inventive method employs wavelet analysis to extract the captured motion vector of different actors into wavelet coefficients, and thus forms a feature vector by optimization selection, which is used later for identification purposes. When the inventive method is applied to process animation frames, the performance can be evaluated by grouping and classification matrix without any correlation with the type of the motion. Also, even if the type of the motion is not stored in the database in advance, the motions of the actor can still be recognized by a learning module regardless of the type of the motions.
