Dear Sir,
I got error when run the code of mask rcnn.
the error like below
but all the step I was follow correctly.
Unrecognized function or variable 'gasonMex'.
Error in gason (line 53)
out = gasonMex( 'convert', in );
Error in CocoApi (line 61)
coco.data=gason(fileread(annFile)); end
Error in unpackAnnotations (line 7)
coco = CocoApi(annotationFile);

Hi,
It appears that you are currently working on instance segmentation using Mask R-CNN and using the COCO API for MATLAB to access the annotation data; however, you are running into an error that "gasonMex" is unrecognized.
This error causing is because the gason parser is not being compiled. To compile it, follow the instruction below:
  • Clone the COCO API GitHub repository as using the following command:
git clone https://github.com/cocodataset/cocoapi
  • In MATLAB, change your current directory to "cocoapi/MatlabAPI".
  • Ensure that your system has a version of GCC that supports C++11 (version 4.7 or later).
  • To compile the gason parser, execute the following MATLAB command:
mex('CXXFLAGS=$CXXFLAGS -std=c++11 -Wall','-largeArrayDims','private/gasonMex.cpp','../common/gason.cpp', '-I../common/','-outdir','private');
Refer to the following links for a better understanding;

  • https://github.com/cocodataset/cocoapi
Regards,
Shivam
