+In this repository, we provide the evaluation code used to generate the weak localization cues and final segmentations from Section 5 (Performance Evaluation) of the paper. The code release enables reproducing the results in our paper. The Keras implementation of HistoSegNet was adapted from [hsn_v1](https://github.com/lyndonchan/hsn_v1); the Tensorflow implementations of SEC and DSRG were adapted from [SEC-tensorflow](https://github.com/xtudbxk/SEC-tensorflow) and [DSRG-tensorflow](https://github.com/xtudbxk/DSRG-tensorflow), respectively. Pretrained models and evaluation images are also available for download.
