利用 OpenCV库，可实现基本的图像边缘检测，计数功能-Using OpenCV library, may realize the basic image edge detection, count function

使用opencv 实现Seamcarving，其中包含梯度和边缘显著度检测对图像进行预处理，智能缩放鲜果更好一些-Use opencv achieve Seamcarving, which contains a significant gradient and edge detection for image pre-processing, intelligent scaling fruit is better
