Thank you for everything.. @supra56

Hello, im new on OpenCV.

I Have a picture like this;

I wrote code like this;

        image = cv2.imread("photos/testtt.png")
        gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
        edged = cv2.Canny(image, 170, 490)
        (cnts, _) = cv2.findContours(edged.copy(), cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)
        idx = 0
        for c in cnts:
            x,y,w,h = cv2.boundingRect(c)
            if w>50 and h>50:
                idx+=1
                new_img=image[y:y+h,x:x+w]
                cv2.imwrite(str(idx) + '.png', new_img)
        cv2.imshow("im",image)
        cv2.waitKey(0)

There are rectangles in the photo, but this code I wrote does not detect these rectangles. I guess I'm not sure, as it leaves very thinly.

I would be very grateful if you could help me, good day everyone.

By the way yes, i want draw each gray area rectangle and save them. @supra56

My goal is to choose only these gray rectangles. Thank you very much for the code you wrote, but it does not work in th

Hello again @supra56 i edited image on first post. Really thank you for helping.
