Numpy 中的 ravel() 和 flatten()两个函数可以对多维数据进行扁平化操作。 flatten() 返回的是一个数组的的副本,新的对象;ravel() 返回的是一个数组的非副本视图。 示例: 代码语言:javascript 复制 numbers=[i*10+jforiinrange(1,5)forjinrange(1,5)]arr=np.array(numbers).reshape(4,4)arr 1、flatte...
im_src = cv2.imread('book2.jpg') # Four corners of the book in source image pts_src = np.array([[141, 131], [480, 159], [493, 630],[64, 601]]) # Read destination image. im_dst = cv2.imread('book1.jpg') # Four corners of the book in destination image. pts_dst = np...
Ran in: "However this seems not to hold." It most certainly does hold! Lets try it. Your example 3D array: formatcompact x = cat(3,eye(3), eye(3), eye(3)) x = x(:,:,1) = 1 0 0 0 1 0 0 0 1 x(:,:,2) = 1 0 0 0 1 0 0 0 1 x(:,:,3) = 1 0 0 0 1...
NumPy - Flattening Arrays - Flattening arrays in NumPy refers to the process of converting a multi-dimensional arrays into a one-dimensional array, where all elements are placed sequentially. This means that regardless of the dimensions (whether it's a 2
