In App Designer, how can I utilise Image Labeler?

Currently, I am developing an app that involves object detection and would like to use Image Labeler as part of it. How would I go about implementing essentially an app within an app?

Hello,

I understand that you want to perform object detection and use Image Labeler in your app.

Image Labeler app provides an easy way to mark the region of interest (ROI) labels interactively. This being an external app, it is not possible to implement this app within another app.

However, as a workaround, you can programmatically load and process the images separately using “imageLabeler” function. Make sure that the images are readable using the “imread” function. Refer to the below code for more clarity.

% To programmatically load a folder of images:
imageFolder = fullfile(toolboxdir('vision'),'visiondata','bookcovers')
imageLabeler(imageFolder)

You can refer to the below documentation to understand more about the “imageLabeler” and “imread” function.
