An Effective Method for Calculating the Area of Enclosed Region

It is a frequently encountered problem to calculate the area of target region in image processing. Based on an improved algorithm of contour extracting, a method for calculating the area of target region was advanced. First, the contour is extracted from the binary image, while note the location and type information of the contour points. Next, the area of target region is calculated by weighting summation of the contour points. Experimental results show this method is simple and easy to implement.
