I get code from your example.

Error:

Traceback (most recent call last):
  File "/var/www/examples/CornerRectangle.py", line 14, in <module>
    lmList, bbox = detector.findPosition(img, draw=False)
AttributeError: 'HandDetector' object has no attribute 'findPosition'

Then I try to install all this packages globally (without venv), and have the same error.

Where is an error?

mediapipe renamed FACE_CONNECTIONS to FACEMESH_TESSELATION . please fixed it

I tried to test the FPS sample code in the documentation and I get the error below. I also tried all of the other examples but then all dont work for me. I am using macOS, python==3.9.5, opencv-python==4.5.2.54 and cvzone==1.5.6

What should I do to fix this?

The hands always get some error/micro moves per frame even if the hand is stand still, so I added a method to eliminate it by using numpy's allclose() function and catching, a new parameter is added named "stabilizerVal" which indicates how many pixels should any of the hand points move to count as a hand movement.

Every landmark was unpacked in only two variables, so giving a normal 3D landmark as input raises errors, so I just omitted the third input (the z value).

FACE_CONNECTIONS no longer exists, I recommend using FACEMESH_CONTOURS to get the outlines of the face.

Draw text with blur or colour background

Text Blur background Function

This function simply calculates the size of input text and add crops the ROI, apply the blur to ROI, and merge with the image, draws text, on that region. It has one, a bug 🐛 since where crop region if text, can't go beyond image bounders, hance crash 😟 , how can I fix this? any suggestion ❤️

Text Color background with opacity Function

This function Calculate the size of input text and creates a colour background with transparency, draw a rectangle copy of img, and add the image back with the OpenCV function, addWeighted, to provide transparency.

The output looks something like that.

It's my first ever contribution to any project, Sir your kind suggestion will help me a lot.

Hi! I get that error " module 'cvzone' has no attribute 'SerialObject' ". And this is my code:

import cvzone import cv2 from cvzone.HandTrackingModule import HandDetector

cap = cv2.VideoCapture(1) #detector= cvzone.HandDetector(maxHands=1, detectionCon=0.7) detector = HandDetector(maxHands=1, detectionCon=0.7) mySerial = cvzone.SerialObject("COM3", 9600, 1)

Unpacking only two values from the points tuple forces the user to recreate a manipulated tuple before passing it to the function, ignoring the 3rd value by default makes the work flow more flexible.

In SerialModule.py, in getData() line 67: the block of code containing the readLine() should be within a try block, maybe something like this (although there may be a better way):

    def getData(self):
        """
        :param numOfVals: number of vals to retrieve
        :return: list of data received
        """
        try:
            data = self.ser.readline()
            data = data.decode("utf-8")
            data = data.split('#')
            dataList = []
            [dataList.append(d) for d in data]
            return dataList[:-1]
        except Exception as e:
            print(e)
            self.ser.close

Exception has occurred: ModuleNotFoundError No module named 'cvzone' File "C:\Users\Bella\Desktop\sign language\venv\test'.py", line 1, in from cvzone.HandTrackingModule import HandDetector

hi! i have already installed cvzone and restarted my laptop, how can I fix this error?

from cvzone.HandTrackingModule import HandDetector import cv2

cap = cv2.VideoCapture(0) detector = HandDetector(detectionCon=0.8, maxHands=2) while True: # Get image frame success, img = cap.read() # Find the hand and its landmarks hands, img = detector.findHands(img) # with draw # hands = detector.findHands(img, draw=False) # without draw

if hands:
    # Hand 1
    hand1 = hands[0]
    lmList1 = hand1["lmList"]  # List of 21 Landmark points
    bbox1 = hand1["bbox"]  # Bounding box info x,y,w,h
    centerPoint1 = hand1['center']  # center of the hand cx,cy
    handType1 = hand1["type"]  # Handtype Left or Right

    fingers1 = detector.fingersUp(hand1)

    if len(hands) == 2:
        # Hand 2
        hand2 = hands[1]
        lmList2 = hand2["lmList"]  # List of 21 Landmark points
        bbox2 = hand2["bbox"]  # Bounding box info x,y,w,h
        centerPoint2 = hand2['center']  # center of the hand cx,cy
        handType2 = hand2["type"]  # Hand Type "Left" or "Right"

        fingers2 = detector.fingersUp(hand2)

        # Find Distance between two Landmarks. Could be same hand or different hands
        length, info, img = detector.findDistance(lmList1[8], lmList2[8], img)  # with draw
        # length, info = detector.findDistance(lmList1[8], lmList2[8])  # with draw
# Display
cv2.imshow("Image", img)
cv2.waitKey(1)

cap.release() cv2.destroyAllWindows()

I got the code from the examples here
