Segment cell organelles with pixellib
I am the creator of PixelLib. PixelLib supports instance segmentation of 80 classes of objects using pre-trained coco model. Cell organelles is not part of the classes supported.
The only solution is to train your own custom model. PixelLib supports custom training of a model using your own labelled dataset. Read this article I published on how to train a custom model with PixelLib.
