Organelles play essential roles in cellular function, but conventional fluorescent labeling limits
observation to one organelle at a time. Super-resolution shadow imaging provides marker-free visualization of
multiple organelles simultaneously. This study focuses on extracting mitochondria from shadow images using
deep learning–based segmentation. To evaluate how training data influence performance, we prepared different
types of ground-truth images and compared their impact on extraction accuracy. Results show that annotation
differences substantially affect segmentation quality, particularly at ambiguous boundaries. These findings
highlight the importance of appropriate ground-truth design for reliable organelle extraction from shadowbased
imaging.
