An Algorithm for Visual Code Marker Extraction and Processing

We present the design, implementation and performance evaluation of an algorithm devised for detection, extraction, and processing of visual code markers in images obtained via low-resolution cameras. The algorithm employs a myriad of techniques to locate, extract, and process the visual code markers for embedded binary data. The system performance has been assessed on a set of training images, and the algorithm has been observed to demonstrate high coherence in code marker detection and low bit-error-rate in binary data extraction. The algorithm also exhibits a significantly low execution time, which hints at its feasibility for implementation in low-power mobile devices.
