Hi everyone I want to know is there any datastore that stores both pixels and rectangle bonding boxes .As we know boxlabeldatastore store rectangle bonding boxes and pixellabeldatastore store polygon bounding boxes. So I want to know is there any that stores both of these bounding boxes in single so That I can train my faster-RCNN for object detection.Thank you

Hi ahmad,

In MATLAB, there is no specific built-in mixed-format label datastore that combines both pixel-level masks and rectangle bounding boxes. However, you can create a custom solution to handle both types of annotations together.

One possible approach is to create a custom datastore that combines the pixel-level masks and rectangle bounding boxes. You can use the imageDatastore to load the images and create a table or structure to store the corresponding pixel-level masks and rectangle bounding boxes. Then, you can iterate over the images and load the annotations, associating them with the respective images.
