OBJ-GSP (AAAI 2025)

Official implementation of AAAI 2025 paper "Object-level Geometric Structure Preserving for Natural Image Stitching".

Install

1. Compile Opencv 4.4.0, VLFEAT and Eigen locally.

2. Create a new Visual Studio .sln, and add all .cpp and .h files into this .sln.

3. Set HED file paths in EdgeDetection.cpp.

StitchBench

StitchBench is by far the most comprehensive image stitching dataset. A sample image pair is provided in ./input-data/AANAP-01_skyline. StitchBench is available at: HuggingFace. You will be automatically granted access to it.

Aerial234

Aerial234 is a open-source dataset of 234 aerial images for image stitching. We used a drone to continuously scan an area of Southeast University and collected this dataset. It’s quite a challenging dataset, and we’re curious if there’s a method to stitch these 234 aerial images into a single panorama.

Aerial234 is available at: HuggingFace.

Our work on aerial image stiching (just a preliminary attempt): UAV image stitching by estimating orthograph with RGB cameras.

Segment Anything Model Script

Run .sln and you will find 0-original.png in the ./ folder. Upload the image to Google Colab and run sam.ipynb to get SAM features and put it in ./ folder.
