How to compare ground truth with segmented image?

I have segmented images of a brain MRI and I have a ground truth that is in .mat format. There are various parameters online such as Dice to compare, but how exactly do I go about with it since the segmented image is in .jpg and ground truth is in .mat? Is there any code that implements any of the segmentation evaluation that I can refer to?
