hello, I have the coordinates of objects in the image and the path of the image and I want to combine all these in the cell array

trainingData = combine(bldsTrainT,bldsTrainW); % this function to combine

when adding the path of the image, display the error

how can instead this function with others to accept the path

Are you referring to combine for augmented image data store?

If so then each element you combine, such as bldsTrainT, must be a data store, not a path itself. You would imageDatastore to wrap the path into an image data store and combine.

insertShape only permits a cell array for "line", "polygon", or "filled-polygon". If you want to plot more than one rectangle you need to use a numeric array

RGB = insertShape(I,'Rectangle', [bbox1; bbox2] );

Hi, I wanted to second Walter's answer which will work best if you want to read the filenames as image data.

However if you do really want the raw filenames in the CombinedDatastore, you can use ArrayDatastore to wrap the filenames before calling combine:

filenames = {'file1.png' 'file2.png'}';
filenameDs = arrayDatastore(filenames, OutputType="same");
trainingData = combine(bldsTrainT,bldsTrainW, filenameDs);
% Or use "transform" to get more control over the combination method
trainingData = transform(bldsTrainT, bldsTrainW, filenameDs, ...
                         @(trainT, trainW, filename) {trainT trainW filename});
