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
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...
(and not N,N-1,N-2 etc as in C-manner). One would expect that, when one tries to reduce the dimensions of an array using colons, the reduction will be done in the same manner as the accessing. However this seems not to hold. For example, we have an array A with dimensions (X...
