CV_32FC1则表示存取的数据是32位float数据,C是Channel,表示1通道。如果是double数据,写出CV_64FC1。 如果是存取图片数据,因为像素信息在0~255之间,可以用8位无符号表示,所以可以写出CV_8UC1(灰白图片)或CV_8UC3(彩色图片) Mat featureMat = Mat(Size(columnNumber, <span style="font-family: Arial, Helvet...

# 从图像文件加载图像并存储到Mat对象中 img = cv2.imread('path_to_your_image.jpg') 总结来说,OpenCV提供了多种方法来初始化Mat对象,你可以根据自己的需求选择合适的方法。无论是创建空矩阵、全零矩阵、全一矩阵、单位矩阵,还是使用数组或图像来初始化,OpenCV都提供了简洁而强大的接口来实现这些功能。
