python定义一个卷积函数

好的，下面是 Python 定义一个卷积函数的代码：

import numpy as np

def convolve(image, kernel):
    height, width = image.shape
    k_height, k_width = kernel.shape
    h_pad = k_height // 2
    w_pad = k_width // 2
    padded_image = np.pad(image, ((h_pad,h_pad),(w_pad,w_pad)), 'constant')
    output = np.zeros((height, width))
    for i in range(height):
        for j in range(width):
            roi = padded_image[i:i+k_height, j:j+k_width]
            output[i,j] = np.sum(roi * kernel)
    return output

请问您还有其他问题吗？
