tmpLbl = np.zeros(label.shape)
tmpLbl = np.zeros(label.shape)是一个将label数组的形状作为参数,创建一个与label形状相同的全零数组的操作。这个操作使用了NumPy库中的zeros函数,该函数可以返回一个给定形状和类型的全零数组。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

drawing = np.zeros(img.shape[:], dtype=np.uint8)
This line of code creates a numpy array called 'drawing' with the same shape as the input image (img) and data type 'unsigned integer 8-bit' (dtype=np.uint8). The array is initialized with all values set to zero.
This is commonly used in computer vision and image processing tasks to create a blank canvas where we can draw lines, shapes or other objects on top of the input image. The resulting 'drawing' array can then be overlaid onto the original image to visualize the changes made.
