Laplacian Pyramid Reconstruction and Refinement for Semantic Segmentation

This repository contains code and models for the method described in:

Golnaz Ghiasi, Charless C. Fowlkes, "Laplacian Pyramid Reconstruction and Refinement for Semantic Segmentation", ECCV 2016

The code is written in Matlab, it uses Matconvnet library and is based on the following repository:


This code is tested on Linux using matconvnet v1.0-beta20 and cuDNN 5

Testing pre-trained models

Download pre-trained models and extract it into models directory.

Testing pre-trained model on PASCAL VOC validation data

Specify matconvnet path in "LRRTestOnPascal.m" and execute it.

Testing pre-trained model on Cityscape validation data

Download "gtFine_trainvaltest.zip" and "leftImg8bit_trainvaltest.zip" from Cityscapes dataset website, unzip them. Specify their path ("opts.dataDir") and matconvnet path ("path_to_matconvnet") in "LRRTestOnCityScape.m" and execute it.

Training LRR on PASCAL VOC training data

Specify matconvnet path in "LRR4xTrainVGG16Pascal.m" and execute it.
