Flip matrix horizontally python

WebMar 24, 2024 · Additionally, it can be used in image processing applications to flip images horizontally or vertically. Syntax: numpy.flip (m, axis=None) Parameters: Return value: out : array_like - A view of m with the entries of axis reversed. Since a view is returned, this operation is done in constant time. Webtorch.flip makes a copy of input ’s data. This is different from NumPy’s np.flip , which returns a view in constant time. Since copying a tensor’s data is more work than viewing that data, torch.flip is expected to be slower than np.flip. Parameters: input ( Tensor) – the input tensor. dims ( a list or tuple) – axis to flip on Example:
