Quick identification method for binary image connected domain marker

The invention discloses a quick identification method for a binary image connected domain marker. The quick identification method comprises the steps: initializing a CPU (central processing unit) and a GPU (graphics processing unit); scanning an image; storing scanning results in a magnetic disk of a server environment; combining the scanning results; judging whether iterative scanning exists, and storing a result to end the operation. The quick identification method has the advantages of capability of improving efficiency, suitability for parallelization and real-time processing of large images.
