QUESTION

I have a list which copies itself or appends itself every time I run my program and I really don't understand (python with opencv)

Asked 2021-Jun-01 at 18:35

I'm actually coding a Multitracker with Opencv using a CSRT tracker. (I used a online code and modified it as I need, here is the source: https://learnopencv.com/multitracker-multiple-object-tracking-using-opencv-c-python/ ) Every time a bounding box is 'updated' its coordinates are added to a list.

For every bbox (bounding box) I have to lists, one for the x and y coordinates of the top left corner of the bbox, and an other one for the x and y coordinates of the bottom right corner. (Those lists are respectively called p1 and p2.)

I have done almost everything that I want, but the p2 list of the bbox 1 don't stop copying itself or something like in the p2 list of the third bbox, and it don't depend of how much bbox exists. Note that I don't want any comments about improving it or optimizing it I don't care about it. Note too that the program is made to run with up to 6 bbox, and it's normal I don't need more but the program can run with 1, 2, or least that 6 bbox if I want.

If I'm lucky it's a stupid error, but I can't get it, so maybe that looks from other peoples on it may find it better than I can! ^^

Here is my long, unoptimized and ugly program! (And thanks if you help me!):

Well after reading it almost 3 times I understood. Using lists which had siblings names wasn't a good thing to do same if I can't do it in an otherway, I was just printing an other list x3

QUESTION

How to make OpenCV tracking classes derive from a base class?

Asked 2021-Apr-19 at 10:06

OpenCV tracking API has implementations in 3 different places.

video/tracking.hpp
tracking.hpp
tracking/tracking_legacy.hpp

I would like to be able to use any implementation by providing the name of the algorithm as input.

ANSWER

Answered 2021-Apr-19 at 10:06

The solution lies in the example script of OpenCV. (tracking/samples/samples_utility.hpp)

We need to convert cv::legacy::Tracker to the preferred type cv::Tracker. Just like the different input problem for a function, we need to implement these member functions separately.

I want to answer this question with the help of this article which I also used before and met the similar problem with yours. Here are the suggestions:

Run YOLOv3 with darknet framework which will increase the performance.
In your code snippet, it looks it doesn't let you to decide network input width and height so I don't know what you are using for them. Decreasing network width and height will increase the speed but oppositely decrease the accuracy.
YOLOv3 trained for 80 objects but you only need some of them. I also only needed the cars in my project before. Unfortunately, you can't manipulate the weight file which is already trained and also you can not train your objects such well.
The other way I also tried before is that I transfered YOLOv3 to another thread and I also didnt apply yolo to all frames. I only applied some of them, for example: 1 frame of each 10 frame. This was also helpful for me.
Or you can choose a better cpu pc :)

How to use the CSRT Tracker correctly to track objects in OpenCV

Asked 2021-Jan-04 at 18:43

I've tried to use the CSRT tracker from OpenCv V4.5.1 to track faces inside video sequences, at the end of some videos I get this error which I can't understand why does it happen!

I'm using AVDIAR dataset
can you please advise me how to use the tracker correctly with Viola-Jones face detector?

Note: wen I used KCF Tracker things worked perfectly! tracker = cv2.TrackerKCF_create()

The solution was to declare a tracker for each object, and initiate that tracker once as following:

You construct the cap object only in case the tracker type is median flow:
