通过NumPy的np.flip()函数可以轻易地翻转数组。 importnumpyasnp# 使用NumPy的flip函数my_array=np.array([[1,2,3],[4,5,6]])flipped_array=np.flip(my_array)print(flipped_array)# 输出:# [[6 5 4]# [3 2 1]] 1. 2. 3. 4. 5. 6. 7. 8. 9. flip的应用场景 数据处理:在数据处理中,...
size2 = int(h*(downsamples[0]/downsamples[2])) # 计算k下的总高 region = np.array(slide.read_region((0, 0), 2, (size1, size2)))#先读取,再数组化 #[m, n] = slide.dimensions print(w, h) #print(downsamples[0]) print(size1, size2) plt.figure() plt.imshow(region) plt.s...
flip适用于所有的数组翻转,而flipud和fliplr一般用于图像(2维数组)的翻转,前者是对图像进行上下翻转,后者是左右翻转 参考:python numpy 矩阵左右翻转/上下翻转 2.1 flip numpy.flip(m, axis=None) Reverse the order of elements in an array along the given axis.The shape of the array is preserved, but th...
该操作的实质是它使用 ::-1 的一个或多个实例(即 slice(None,None,-1) )为您的数组编制索引。 flipud/lr 做同样的事情。 有了这个 x, flip 做: In [826]: np.array([1,2,3])[::-1] Out[826]: array([3, 2, 1]) 原文由 hpaulj 发布,翻译遵循 CC BY-SA 3.0 许可协议 有用 回复 ...

The numpy.flip() function is used to reverse the order of elements in an array along the given axis. The shape of the array is preserved, but the elements are reordered. The function reverse the order of elements in an array to help with processing data in reverse order, or to transform...
