    摘要: The present invention is a system and method for decoding an image of a bar code. Decoding the barcode includes tokenizing a plurality of pixels in the image of the barcode based upon a plurality of thresholds to form a first set of tokens. Decoding the barcode also includes re-tokenizing the plurality of pixels in the image of the barcode based upon the intensity of the pixels in the plurality of tokens, and the relativity intensity of neighboring tokens, to form a second set of tokens.

    摘要: Methods and systems for detecting and compensating for motion depicted in a sequence of frames are disclosed. One example method includes converting video frames to monochrome. Conversion of an image to monochrome includes sampling luminance data of a portion of pixels in the image to identify the image as being of a particular image type, selecting a bit plane of the image based on the identified image type, and converting the image to a monochrome image using the selected bit plane. After conversion of video frames to monochrome, a pixel subset in a monochrome image corresponding to a first frame is compared to candidate matching pixel subsets within a search area of a monochrome image corresponding to a second, consecutive frame. The frames are processed to compensate for perceived motion blur based on the detected inter-frame motion.

    摘要: A method and system for displaying frames on a hold-type display to reduce perceived blur are disclosed. One example method includes detecting a parameter associated with an object in an input frame and filtering the input frame to generate at least two filtered sub-frames based on the parameter. The filtered sub-frames are then inserted in place of the input frame in a frame sequence and output to a display. The parameter associated with the object may indicate a magnitude and direction of the object's movement in a sequence of frames including the input frame.
