Abstract

Panoramic image segmentation in computational pathology presents a remarkable challenge due to the morphologically complex and variably scaled anatomy. For instance, the intricate organization in kidney pathology spans multiple layers, from regions like the cortex and medulla to functional units such as glomeruli, tubules, and vessels, down to various cell types. In this paper, we propose a novel Hierarchical Adaptive Taxonomy Segmentation (HATs) method, which is designed to thoroughly segment panoramic views of kidney structures by leveraging detailed anatomical insights.

Our approach entails <br /> (1) the innovative HATs technique which translates spatial relationships among 15 distinct object classes into a versatile “plug-and-play” loss function that spans across regions, functional units, and cells, <br /> (2) the incorporation of anatomical hierarchies and scale considerations into a unified simple matrix representation for all panoramic entities, <br /> (3) the adoption of the latest AI foundation model (EfficientSAM) as a feature extraction tool to boost the model’s adaptability, yet eliminating the need for manual prompt generation in conventional segment anything model (SAM). Experimental findings demonstrate that the HATs method offers an efficient and effective strategy for integrating clinical insights and imaging precedents into a unified segmentation model across more than 15 categories.

Model Training

  1. Use Dataset_save_csv.py to generate data list csv.
  2. Use train_EfficientSAM_HATs.py to train the model.
  3. Use Testing_EfficientSAM.py to test the model.

How to define the segmentation model

We provide two model backbones: <br />

  1. a dynamic EfficientSAM backbone from HATs: <br /> DynamicEfficientSAM<br />
import os, sys
sys.path.append("/Data4/HATs/EfficientSAM_token_dynamichead_logits")
from efficient_sam.build_efficient_sam import build_efficient_sam_vitt, build_efficient_sam_vits

model = build_efficient_sam_vits(task_num = 15, scale_num = 4)
model.image_encoder.requires_grad_(False)
  1. a token-based CNN backbone from PrPSeg: <br /> TokenOmniSeg<br />
from unet2D_Dodnet_scale_token import UNet2D as UNet2D_scale

model = UNet2D_scale(num_classes=15, num_scale = 4, weight_std=False)

How to define the Hierarchical Adaptive Taxonomy matrices

  1. Hierarchical Scale Matrix
Area = np.zeros((15))
Area[0] = 2.434
Area[1] = 2.600
Area[2] = 1.760
Area[3] = 1.853
Area[4] = 1.844
Area[5] = 0.097
Area[6] = 0.360
Area[7] = 0.619
Area[8] = 0.466
Area[9] = 0.083
Area[10] = 0.002
Area[11] = 0.012
Area[12] = 0.001
Area[13] = 0.001
Area[14] = 0.002

def division_ratio(a, b):
	if a > b:
		return b / a
	else:
		return a / b

Area_ratio = np.zeros((15, 15))
for xi in range(0,15):
    for yi in range(0,15):
        Area_ratio[xi,yi] = division_ratio(Area[xi], Area[yi])
