imagedatastore grayscale to rgb for maskRcnn

• I have several CT images : ct1, ct2, ct3.....
• Each CT contains of aprox 90 2D grayscale images/planes
• MaskRCnn Requires RGB Input

How do I looup through each CT and save each image within a CT as own image in the datastore?

I also need it as RGB image, where only one plane is set with the grayscale and the reast to 0 or 1.

Hope someone can help me!

You may convert the gray image to 3D array planes

rgb_gray=cat(3,gray_image,gray_image,gray_image);

Just do for one images, for all images can be done using call one individual images at a time using loop. There are so many simmilar threads are available.

Thank you for your help!

I am not sure about the looping. Can I do it somehow in the read function or do I have to do it from "outside" ?
