你已经正确地导入了sys, cv2,和 numpy这三个库。在Python中,使用cv2库(OpenCV)进行图像处理是非常常见的,而numpy则是进行高效数值计算的基础库。sys库通常用于与Python解释器交互,虽然在这个特定的代码片段中可能并不需要它,但导入它也没有问题。 加载输入图像: 接下来,你需要加载名为table.jpg的图像文件。这可以...

OpenCV makes reading a wide range of image file types from disk a breeze with thecv2.imreadfunction. We load the input--imageto memory onLine 13usingcv2.imread, which returns theimageas a NumPy array. Upon success, we obtain the image dimensions(h, w, c)from the shape of the array (...

Your image is loaded - with the correct orientation! By default, the image array is returned as a numpy array with 3-channels of 8-bit RGB data. You can control the output format by passing in an optionalmodeparameter: importimage_to_numpyimg=image_to_numpy.load_image_file("my_file.jpg...
