Examples

Hand Tracking

from cvlearn import HandTrackingModule as handTracker
import cv2

cap = cv2.VideoCapture(0)
detector = handTracker.handDetector()

while True:
    ret, img = cap.read()
    img = detector.findHands(img)
    
    cv2.imshow("Result", img)
    cv2.waitKey(1)

Result:

---

Face Detection

from cvlearn import FaceDetection as faceDetector
import cv2

cap = cv2.VideoCapture(0)
detector = faceDetector.FaceDetector()

while True:
    ret, img = cap.read()
    img = detector.findFaces(img)
    
    cv2.imshow("Result", img)
    cv2.waitKey(1)

Face Mesh

from cvlearn import FaceMesh as fms
import cv2

cap = cv2.VideoCapture(0)
detector = fms.FaceMeshDetector()

while True:
    ret, img = cap.read()
    img, face = detector.findFaceMesh(img)

    cv2.imshow("Result", img)
    cv2.waitKey(1)

Finger Counting

from cvlearn import FingerCounter as fc
import cvlearn.HandTrackingModule as handTracker
import cv2

cap = cv2.VideoCapture(0)
detector = handTracker.handDetector(maxHands=1)
counter = fc.FingerCounter()

while True:
    ret, frame = cap.read()
    frame = cv2.flip(frame, 180)

    frame = detector.findHands(frame)
    lmList, bbox = detector.findPosition(frame)

    if lmList:
        frame = counter.drawCountedFingers(frame, lmList, bbox)

    cv2.imshow("res", frame)
    key = cv2.waitKey(1)
    if key == 27:
        break

cv2.destroyAllWindows()

Two Hands Finger Counting

from cvlearn import TwoHandsFingerCounter as fc
import cv2

cap = cv2.VideoCapture(0)
counter = fc.FingerCounter()

while True:
    ret, frame = cap.read()
    frame = counter.drawCountedFingers(frame)

    cv2.imshow("res", frame)
    key = cv2.waitKey(1)
    if key == 27:
        break

cv2.destroyAllWindows()

Pose Detection

import cv2
import cvlearn
from cvlearn import PoseDetector, Utils

cap = cv2.VideoCapture(0)
detector = PoseDetector.PoseDetector(detectionCon=0.5, trackCon=0.5)

while True:
    success, img = cap.read()
    img = detector.findPose(img)
    lmList = detector.findLandmarks(img)

    cv2.imshow("Image", img)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

cap.release()
cv2.destroyAllWindows()
