Hello, thank you for sharing. I'm a beginner. I want to know how label and GIF animation works. Can you tell me? Thank you.

Hi, the labels are segmentation masks from radiologists. They are essentially contours depicting the regions of interest (tumor in this case). They are formatted in a way that the pixels inside the contours have non-negative values (typically 1) while those outside the contours are 0s. For visualization, we overlaid the segmentation masks on top of the original MRI slices and assembled them sequentially to generate the GIF animation with Convert command from the ImageMagick package.
