Python computer vision help i just started out

[Symbolls]

Hello so i have been galowing a tutorial on computer vison (https://www.murtazahassan.com/courses/opencv-with-python-for-beginners/lesson/object-tracking/) for object traking i downloaded the code witch is

 

import cv2

############### Tracker Types #####################

# tracker = cv2.TrackerBoosting_create()
# tracker = cv2.TrackerMIL_create()
# tracker = cv2.TrackerKCF_create()
# tracker = cv2.TrackerTLD_create()
# tracker = cv2.TrackerMedianFlow_create()
# tracker = cv2.TrackerCSRT_create()
tracker = cv2.TrackerMOSSE_create()

########################################################


cap = cv2.VideoCapture(1)
# TRACKER INITIALIZATION

success, frame = cap.read()
bbox = cv2.selectROI("Tracking", frame, False)
tracker.init(frame, bbox)


def drawBox(img, bbox):
    x, y, w, h = int(bbox[0]), int(bbox[1]), int(bbox[2]), int(bbox[3])
    cv2.rectangle(img, (x, y), ((x + w), (y + h)), (255, 0, 255), 3, 3)
    cv2.putText(img, "Tracking", (100, 75), cv2.FONT_HERSHEY_SIMPLEX, 0.7, (0, 255, 0), 2)


while True:

    timer = cv2.getTickCount()
    success, img = cap.read()
    success, bbox = tracker.update(img)

    if success:
        drawBox(img, bbox)
    else:
        cv2.putText(img, "Lost", (100, 75), cv2.FONT_HERSHEY_SIMPLEX, 0.7, (0, 0, 255), 2)

    cv2.rectangle(img, (15, 15), (200, 90), (255, 0, 255), 2)
    cv2.putText(img, "Fps:", (20, 40), cv2.FONT_HERSHEY_SIMPLEX, 0.7, (255, 0, 255), 2);
    cv2.putText(img, "Status:", (20, 75), cv2.FONT_HERSHEY_SIMPLEX, 0.7, (255, 0, 255), 2);

    fps = cv2.getTickFrequency() / (cv2.getTickCount() - timer);
    if fps > 60:
        myColor = (20, 230, 20)
    elif fps > 20:
        myColor = (230, 20, 20)
    else:
        myColor = (20, 20, 230)
    cv2.putText(img, str(int(fps)), (75, 40), cv2.FONT_HERSHEY_SIMPLEX, 0.7, myColor, 2);

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

i am using pycahrm btw and i keep having this error

 

File "C:\Users\symbo\PycharmProjects\OpencvTest\main.py", line 11, in <module>
    tracker = cv2.TrackerMOSSE_create()
AttributeError: module 'cv2.cv2' has no attribute 'TrackerMOSSE_create'

witch is wierd bechos i have downloaded all the librarys the guy in the video mentioned and i cant seem to be able to get rid of it. i now it means that a cirtone module or code is missing and i cant download an older version of this pls gelp and thx for reading

How did you install these modules? Did you pip install it?

the program PyCharm alows me to instal with a few clicks.I think the program is running the pip commands for me

Seems like these tracker modes were moved to cv2.legacy instead of cv2, as can be seen here:

https://github.com/opencv/opencv_contrib/blob/f1c3d0e5e789a213ab8ab2828f360e520a3b35ce/modules/tracking/misc/python/test/test_tracking_contrib.py

sorry but i am not realy good with this stuff so wat do you think i shuld do if the trackers whore moved i mean how can i move them back

The code example is written for some older version of the opencv package so either try using one of the older versions or update the code example for current version. With luck it will be just changing imports.

You may be using the wrong version of OpenCV. Check which version of the module your tutorial requires and install that one. Also don't install both. You should install only opencv-contrib-python, as that contains opencv-python already.

For example where the code says "tracker = cv2.TrackerMOSSE_create()", you should now say "tracker = cv2.legacy.TrackerMOSSE_create()".

 

However, judging by "legacy" this could mean this functionality is outdated and will be removed. So either update the code to use the proper convention for the current version, or as I said above check which version the tutorial assumes and use that.
