ObjectnessBING: Failing at assert

[victorhcm]

Hi there,

I'm trying to use BING, but I'm failing at the following assert (line):

CV_Assert( w1f.cols * w1f.rows == D && w1f.type() == CV_32F && w1f.isContinuous() );

I tried different kinds of input; also, tried to force the attributes, but still didn't manage to get it working. Do you know what am I missing?

I'm using OpenCV 3.1.0.

You could change this line to three lines like this

CV_Assert( w1f.cols * w1f.rows == D);
CV_Assert(w1f.type() == CV_32F);
CV_Assert(w1f.isContinuous());

so you will actually know which of the fields are wrong there.

i have the same error:
OpenCV Error: Assertion failed (w1f.cols * w1f.rows == D && w1f.type() == CV_32F && w1f.isContinuous()) in update, file /home/raman/opencv_contrib/modules/saliency/src/BING/FilterTIG.cpp, line 74

to update i did break it down into three lines. its failing on the first one.
w1f.cols and w1f.rows are valued at 0 both while D is 64.

I think its because of the training path or model isnt set properly.. but i am not 100% sure on this.

The command line shows only 3 arguments by default. Adding the path to the trained model as the 4th model fixes this for me. The command line should look something like this:
./computeSaliency BING RGB_VIDEO.avi 1 ObjectnessTrainedModel/

Were you able to fix this problem? I am facing the same problem.

Has the issue been solved?

[anupamsobti]

Did the solution I suggested work for you? I guess we could fix the command line usage printed from the application. Shall I raise a PR?

[AlvarHHM]

I am using the python wrapper to call the API, any idea what went wrong?

[anupamsobti]

It would help if you posted details of the command line you're using and the error you're getting. The original problem was that the trained model was not specified to the script.
