【Abstract】 Objective: To study method of area measurement for the irregular region in the digital image. Methods: At first, the pixels inside the boundary were defined by using both the previous vector and the next vector; and then, the measured area was the result of the whole numbers of the pixels on the boundary and inside the boundary multiplied by a pixel area. At the same time, the method was programmed based on the vector analysis. Results: The method introduced by this paper could correctly detect the pixels inside the boundary, and the area could be measured accurately. Conclusion:The method based on the vector analysis is simple, reliable and effective in the area measurement of the irregular region.更多还原
