Spherical Superpixel

This repository contains the dataset, the evaluation code and the source code of our works on spherical superpixels.

Dataset

Currently, our dataset contains 75 manually annotated spherical panoramas. The original panoramas are selected from SUN360 dataset. Each image is resized to 1024x512 pixels and segmented with an annotation tool based on the application provided by the authors of BSD dataset.

For each spherical panorama, we provide the ground truth segmentations and ground truth boundaries. Some annotation examples are shown below. If you use this dataset in published work, please cite our paper as
