About the function 'nms_mex'

ujjaldas1997 commented 7 years ago

Hello Peiyunh, I am using your code in matlab r2014a. I have encountered the stated issues and rectified them. After that, I have faced a new issue which I can't fixed even though searching online. When running this -- _bboxes = tiny_facedetector('data/demo/selfie.jpg', './selfie.png', 0.5, 0.1, 1) I found the following error

Loading pretrained detector model...
Processing data/demo/selfie.jpg at scale 0.031250.
Error using vl_nnconv
An input is not a numeric array (or GPU support not
compiled).

Error in dagnn.Conv/forward (line 11)
      outputs{1} = vl_nnconv(...

Error in dagnn.Layer/forwardAdvanced (line 85)
      outputs = obj.forward(inputs,
      {net.params(par).value}) ;

Error in dagnn.DagNN/eval (line 91)
  obj.layers(l).block.forwardAdvanced(obj.layers(l)) ;

Error in tiny_face_detector (line 130)
  net.eval(inputs);

As I am using CPU version of matconvnet so I changed gpu = 0 as -- _bboxes = tiny_facedetector('data/demo/selfie.jpg', './selfie.png', 0.5, 0.1, 0) The error is

    pick = nms_mex(double(boxes), double(overlap));

Error in tiny_face_detector (line 172)
ridx = nms(bboxes(:,[1:4 end]), nms_thresh);

I am unable to fix this. Please answer my question. Thank you.

I just found out the issue. Ignore this issue.

hello ujjaldas1997 , I meet the same issue,Do you fix it now? Cause I’m a beginner，I don't know what to do,can you give me more details? thank you.

I have just compiled nms in matlab. The change I have made is as --(in the file /tiny/toolbox/nms/nms.m)

if size(boxes, 1) < 1000000
            mex -O -outdir bin ...
          CXXFLAGS="\$CXXFLAGS -std=c++11"  ...
          -largeArrayDims ...
          toolbox/nms/nms_mex.cpp ...
          -output C:\Users\ujjal\tiny\nms_mex;
    %mex nms_mex.cpp;
    pick = nms_mex(double(boxes), double(overlap));
    return;
end

Change the file path according to your file tree. And then try to run.
