ERF-PSPNET implemented by tensorflow

The code is impledmented according to the following papers.

• Unifying Terrain Awareness for the Visually Impaired through Real-Time Semantic Segmentation
• Unifying terrain awareness through real-time semantic segmentation

tensorflow 1.11
Open CV
Python 3.6.5

This repository serves as a real-time semantic segmentation networks, which is designed for the assistance for visually-impaired people. The code not only implements the tensorflow-version erf-pspnet, but also implements the code for mIOU calculation which haven't been found in other tf-version's code. Our code combines the training and evaluating stages together, which records every claesses' ioU after one epoch, and fulfill visualization supervision during training. In addition, we adapt IAL which is a loss function for pushing model to foucs on important classes. And we implement BiERF-PSPNet which is inspired by BiSeNet.

The useage is very easy, you only need to download the code, and create a file folder named dataset, and create another four file folders under the dataset named train, trainannot, val, valannot ,and put into the data we want to train or eval like the example in the repository.

In the future, I will update the demo code for video, a improved version network and loss-function like IAL for specific tasks.
