Abstract
Image data which includes a feature is labeled. The image data is comprised of pixel data in an N×M array. At least one pixel is designated and flagged. Asynchronous processes are executed, where each process corresponds to exactly one pixel. Each process sets a flag only for the owner pixel and only if a connected neighbor pixel in the pre-defined path is flagged. Each process inspects pixel data for all neighbor pixels of the owner pixel to determine if a neighbor pixel is a connected pixel and if the neighbor pixel is flagged, and continues until it sets the flag for the owner pixel or until all connected horizontal and vertical neighbor pixels have been inspected without encountering a connected neighbor pixel whose flag is set. The asynchronous processes are repeated until a pre-defined condition has been satisfied. All flagged pixels are labeled.
