Dear All,
I want to do the MASK RCNN deep learning method for object detection. (All the data set was attached.)
But I got error like this LINE:
boxmaskpc= table(gTruthnouveau.DataSource.Source(1:9,1), gTruthnouveau.LabelData.ordinateur(1:9,1),...
'VariableNames',{'files','box'});
boxmaskphone= table(gTruthnouveau.DataSource.Source(10:18,1), gTruthnouveau.LabelData.portable(10:18,1),...
'VariableNames',{'files','box'});
BELOW IS MY CODING

Hi mohd,
I Understand that you are facing an issue in accessing “groundTruth” Object. As per the data provided, the “DataSource” of “groundTruth” Object is not created properly.
As per the documentation, “DataSource” can be created in the following way, and then you can create a “groundTruth” Object using the “DataSource”,”LabelDefinitions” and “LabelData”.
%Creating the dataSource
dataSource = groundTruthDataSource(gTruthnouveau.DataSource)
%Creating the groundTruthObject
groundTruthObject = groundTruth(dataSource, gTruthnouveau.LabelDefintions ,gTruthnoveau.LabelData)
Please refer to the following link, for further information,
https://www.mathworks.com/help/vision/ref/groundtruth.html
Hope this helps!
Regards,
Sanjana.

Hi @Sanjana, I got Error
%Creating the dataSource
>> dataSource = groundTruthDataSource(gTruthnouveau.DataSource);
Error using groundTruthDataSource/parseAndPopulateInputs
Cannot find files or folders matching:
'C:\Users\NGSI\Desktop\FasterRCNN_and_MaskRCNN_PC\BDD_ESSAI\02.jpg'.
Error in groundTruthDataSource (line 194)
parseAndPopulateInputs(this, varargin{:});
>> groundTruthObject = groundTruth(dataSource, gTruthnouveau.LabelDefintions ,gTruthnoveau.LabelData);
Unrecognized function or variable 'dataSource'.
