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： An adequate solution for computer vision applications is arrived at more efficiently and, with more automation, enables users with limited or no special image processing and pattern recognition knowledge to create reliable vision systems for their applications. Computer rendering of CAD models is used to automate the dataset acquisition process and labeling process. In order to speed up the training data preparation while maintaining the data quality, a number of processed samples are generated from one or a few seed images.

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, apparatus and image capture device for limiting motion blur during capture of an image predetermines a relationship between movement of the image capture device, time and blur extent. A rate of movement of the image capture device is obtained and used in conjunction with the determined relationship and a blur extent limit as a basis for obtaining a maximum exposure time for the image capture device in order to limit blur extent. On the basis of the maximum exposure time obtained and a required image brightness, the image capture device is configured, and then an image is captured by the image capture device. Once the image has been captured, due to the possibility of under-exposure from having limited the exposure time, the image is processed as required to increase its intensity.
