endPtsOfContours

endPtsOfContours is a concept often encountered in computer vision and image processing, particularly when dealing with contour detection algorithms. A contour is a curve that describes the boundary of a shape or an object within an image. The end points of a contour refer to the starting and ending points of this detected curve. In many algorithms, contours are represented as a sequence of connected points. Therefore, the end points are simply the first and last points in this sequence. Identifying these specific points can be useful for various applications. For instance, in shape analysis, knowing the extremities of a contour might help in calculating properties like length or in determining if a contour is closed. When a contour detection algorithm produces a result, it typically returns a list or array of points. The first and last elements of this list or array are considered the end points. The exact method of contour detection and the subsequent identification of end points can vary depending on the specific library or algorithm being used, such as OpenCV's `findContours` function which often returns contours as lists of points.
