@@ -27,3 +27,6 @@ cv.dilate(src, kernel[, dst[, anchor[, iterations[, borderType[, borderValue]]]]
`src`: 二值化的影像
`kernel`: 捲積 kernel
`iterations`: 迭代次數（預設為1）
## cv2.GaussianBlur()
高斯濾波與平均濾波 Averaging 類似，平均濾波 Averaging 的 kernel 裡的每個 pixel 權重都是1，而高斯濾波給予每個 pixel 不同權重，中心 pixel 的權重最高，越往邊角權重就越低，相較於平均濾波 Averaging 這樣可以讓圖片失真較少，高斯濾波通常去除雜訊也有不錯的效果。
