说明：  针对自然生长状态下的成熟苹果图像的识别问题，提出选用R-G色差模型，改进的Ostu最大类间方差法分割图像。 然后用面积阈值法消除噪声，获取成熟苹果果实的目标区域。然后采用基于OpenCV的圆形Hough变换方法对多个粘连苹果果实进行分离。
(For image recognition problem ripe apples natural growth state, the proposed selection of R-G color model between improved Ostu Otsu segmentation image. Then use the area to eliminate noise threshold, apple fruit get ripe target area. Then based on circular Hough transform OpenCV on multiple adhesions apple fruit separation.)
