This repository contains all the files for you to complete the 'Getting Started with SegNet' and the 'Bayesian SegNet' tutorials here: http://mi.eng.cam.ac.uk/projects/segnet/tutorial.html
Please see this link for detailed instructions.
SegNet requires a modified version of Caffe to run. Please download and compile caffe-segnet to use these models: https://github.com/alexgkendall/caffe-segnet
This version supports cudnn v2 acceleration. @TimoSaemann has a branch supporting a more recent version of Caffe (Dec 2016) with cudnn v5.1: https://github.com/TimoSaemann/caffe-segnet-cudnn5
If you would just like to try out an example model, then you can find the model used in the SegNet webdemo in the folder Example_Models/. You will need to download the weights separately using the link in the SegNet Model Zoo.
First open Scripts/webcam_demo.py and edit line 14 to match the path to your installation of SegNet. You will also need a webcam, or alternatively edit line 39 to input a video file instead. To run the demo use the command:
python Scripts/webcam_demo.py --model Example_Models/segnet_model_driving_webdemo.prototxt --weights /Example_Models/segnet_weights_driving_webdemo.caffemodel --colours /Scripts/camvid12.png
Use docker to compile caffe and run the examples. In order to run caffe on the gpu using docker, please install nvidia-docker (see https://github.com/NVIDIA/nvidia-docker or using ansbile: https://galaxy.ansible.com/ryanolson/nvidia-docker/)
to run caffe on the CPU:
docker build -t caffe:cpu ./cpu
# check if working
docker run -ti caffe:cpu caffe --version
# get a bash in container to run examples
docker run -ti --volume=$(pwd):/SegNet -u $(id -u):$(id -g) caffe:cpu bash
to run caffe on the GPU:
docker build -t caffe:gpu ./gpu
# check if working
docker run -ti caffe:gpu caffe device_query -gpu 0
# get a bash in container to run examples
docker run -ti --volume=$(pwd):/SegNet -u $(id -u):$(id -g) caffe:gpu bash
A number of example models for indoor and outdoor road scene understanding can be found in the SegNet Model Zoo.
