发明名称 CAMERA BASED CODE READING
摘要 Techniques for providing camera based code reading are disclosed. In some aspects, a camera-readable code is generated which may be read by a code reading device. The code reading device may capture an image of the code, process the image, and decode the code. The code includes symbols arranged to form a pattern. According to one or more embodiments, an image with the code is cropped to remove extraneous information. The code image is manipulated by exact binary segmentation to remove background information from the code. The code is oriented to a grid using an interval value defined between the symbols. The symbols are decoded by comparing unique aspects of the symbols using a statistical analysis. The decoded symbols may be converted to a message for a user or be used for other purposes.
