if __name__ == '__main__': cartoon('2.jpg', edge='Canny')

As an AI language model, I do not have access to the function or module `cartoon` and the image file `2.jpg`. However, I can explain what the code is doing.
The code is checking whether the script is being run directly (as opposed to being imported as a module) using the `__name__` variable. If it is being run directly, the `cartoon` function is called with the argument `'2.jpg'` for the image file and the parameter `edge='Canny'` to specify the edge detection algorithm to use. The `cartoon` function presumably applies a cartoon filter to the image, which can be customized with various parameters including the edge detection algorithm.

img_edge = cv2.Canny(img_thresh, 100, 200)
这是一个使用 OpenCV 库中的 Canny 函数对图像进行边缘检测的代码。Canny 函数可以帮助我们找到图像中的边缘,其中 img_thresh 是一个二值化的图像,100 和 200 是 Canny 函数的两个参数,用于控制边缘检测的敏感度。
edges = cv2.Canny(gray_mask, 50, 150)
这段代码使用了OpenCV的Canny函数来进行边缘检测。Canny函数是一种广泛使用的边缘检测算法,其基本思想是在图像中寻找像素值变化最大的点,以此来确定图像中的边缘。Canny函数的参数包括输入图像、低阈值和高阈值,其中低阈值和高阈值用于去除噪声和连接边缘。在这里,gray_mask是输入图像,50和150分别是低阈值和高阈值。这个函数的输出是一个二进制图像,其中像素值为255的点表示边缘,像素值为0的点表示非边缘。
