Problem 1 : Different applications use different scales for HSV. For example gimp uses H = 0-360, S = 0-100 and V = 0-100. But OpenCV uses H: 0-179, S: 0-255, V: 0-255. Here i got a hue value of 22 in gimp. So I took half of it, 11, and defined range for that. ie (5,50,50) - (15,255,255).
Problem 2: And also, OpenCV uses BGR format, not RGB. So change your code which converts RGB to HSV as follows:
cv.CvtColor(frame, frameHSV, cv.CV_BGR2HSV)
Now run it. I got an output as follows:
Hope that is what you wanted. There are some false detections, but they are small, so you can choose biggest contour which is your lid.
EDIT:
As Karl Philip told in his comment, it would be good to add new code. But there is change of only a single line. So, I would like to add the same code implemented in new cv2 module, so users can compare the easiness and flexibility of new cv2 module.
import cv2
import numpy as np
img = cv2.imread('sof.jpg')
ORANGE_MIN = np.array([5, 50, 50],np.uint8)
ORANGE_MAX = np.array([15, 255, 255],np.uint8)
hsv_img = cv2.cvtColor(img,cv2.COLOR_BGR2HSV)
frame_threshed = cv2.inRange(hsv_img, ORANGE_MIN, ORANGE_MAX)
cv2.imwrite('output2.jpg', frame_threshed)
It gives the same result as above. But code is much more simpler.
