Sometimes, the OP segmentation mask shows clearly very large objects that are not detected, that sit next to smaller segmented objects that are in fact detected. Why are these bigger objects not detected?
Has not been addressed. The very most likely explanation, however, is that the objects are detected in terms of being above threshold, but are simply too small to pass the criterion of sufficient volume.
