I just ran some of my own datasets on the CPP version. It worked great, but it was very noisy (keypoints detected all over) in the python version. Why might that be?
As opencv is now available at 3.1, are there any plans to upgrade CMT to work with 3.1
If not is there a particular sweet spot of OpenCV 3 that you found works ?
I'm getting a core dumped fault on ubuntu 14.04 when I run the command
CMT$ python run.py challenge.mp4
challenge.mp4 is located in the CMT directory.
Any help with that is appreciated
I am constantly getting the error below. Can someone help? I have modified the code to run for multiple objects by initializing it with a new region to start with. Please help. It stops throwing this error at times.
Thanks.
File "run2.py", line 136, in
CMT.process_frame(im_gray)
File "/home/shuchita/Documents/Internship/CMT-master/CMT.py", line 245, in process_frame
selected_matches_all = self.matcher.knnMatch(features, self.selected_features, len(self.selected_features))
TypeError: object of type 'NoneType' has no len()
So the original issue was:
"I am trying to run CMT on some of the provided data sets and I am encountering the OpenCV error: Assertion failed (scn == 3 || scn == 4). Any Idea what could be causing this? seems to be called in run.py at line 104."
This seems to be alleviated by adding:
if len(im0.shape) == 3:
im_gray0 = cv2.cvtColor(im0,cv2.COLOR_BGR2GRAY)
else:
im_gray0 = im0
this in turn revealed what I think was the underlying issue. I keep getting that im0 is equal to None or None type meaning that either the program is not finding the specified files of the first frame is blank or "dead". I have looked around and have found some suggestions to try to fix this problem. Most add some code like :
" frame=cvQueryFrame(capture);
if (frame..empty()) break;"
(code from: http://stackoverflow.com/questions/21871540/opencv-error-assertion-failed-scn-3-scn-4?lq=1)
or:
if defects is None: else:
I am trying to fix it but being relatively new to Python I cannot get the program to rid the given video files, both color or gray scale.
When trying to execute lines the following lines ( by pressing 'd') the program has an exception.
https://github.com/gnebehay/CMT/blob/master/run.py#L219-L220
Here is the console output:
Traceback (most recent call last):
File "run.py", line 215, in <module>
ipdb.set_trace()
NameError: name 'ipdb' is not defined
When using sample files there seem to be some differences in the outputs shown than to my result. Number of key points is less in my outputs then in shown results. Key points are also tightly cluster in center of box, all in center are coloured blue. Any points not in exact center of Box are white. None are green like samples, why did this change, is this for newer versions? Also in results like cup on table, the cup is not tracked and is lost very easily by program. I can post output if needed. Sorry for bad english.
Can CMT be used for multiple objects in a frame? If yes, please suggest the best way that could be possible.
Hi Georg
The DESC_LENGTH in your Code is hardcoded 512.
But the dtype of the BRIEF (or ORB) descriptor is uint8 and the length is 32.
I think it should be 8 times 32 = 256 as written in BRIEF: Binary Robust Independent
