感知器算法，利用C语言实现。利用梯度下降法进行迭代求解。-Perception algorithm, using C language, that is, we usually write operations, to share with you. . . .

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
