From: Flexible Learning-Free Segmentation and Reconstruction of Neural Volumes
An example SRB image and the corresponding cell segmentation results of various methods. The FLoRIN reconstruction based on 3D NDNT, along with the raw 3D NDNT segmentation, captures all of the cells with only minor merge errors. All other methods severely over- or under-segment the image, and are susceptible to the grayscale shift in the lower-left corner of the image. The only other methods to come close to the FLoRIN results are Sauvola40 and Triangle41 thresholding in 2D, both of which also struggled with excessive merge errors. Methods labeled with asterisks were applied over 3D blocks of the volume, which in some cases resulted in the white “tiles” in some of the images.
