[英]How to save image in opencv after thresholding using imwrite
我試圖在閾值處理后使用 cv2.imwrite 保存圖像,但它不保存圖像。 下面是我正在使用的代碼:
import necessary packages
ap = argparse.ArgumentParser()
ap.add_argument("-i", "--image", required = True,
help = "Path to the image to be thresholded")
ap.add_argument("-t", "--threshold", type = int, default = 128,
help = "Threshold value")
args = vars(ap.parse_args())
image = cv2.imread(args["image"])
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
methods = [("THRESH_BINARY", cv2.THRESH_BINARY)]
for (threshName, threshMethod) in methods:
(T, thresh) = cv2.threshold(gray, args["threshold"], 255, threshMethod)
cv2.imshow(threshName, thresh)
cv2.waitKey(0)
cv2.imwrite(gray, args["image"])
我想你想保存 thresh 圖像。 cv2.imwrite(args["image"], thresh)
應該在 for 循環內。
