Claim 7:
8. The method according to claim 6, wherein the step of cell reconstruction comprises edge expansion and vertex connection, the step of edge expansion comprising forming an expanded region by expanding the outermost edge of each of four sides of the morphological image outward by a width of at least 1 pixel based on the morphological image, and acquiring an expanded image by setting pixel values of all pixel points in the expanded region to 1; the step of vertex connection comprising traversing the expanded image in an order from left to right and from top to bottom taking the expanded image as an object, and when encountering a pixel point having a pixel value of 0, finding and recording a vertex of the same cell and a connection sequence thereof with a Moore neighborhood tracking algorithm and recording the same under the cell, deleting duplicate records on a principle that each cell keeps at most six vertexes, and drawing a complete cell by connecting the vertexes according to the kept records; then, setting pixel values of all pixel points in the cell to 1; and finding a next pixel having a pixel value of 1 and repeating the operations until the traverse is completed and the reconstructed cell image is also completed.
