NativeSticher

NativeSticher is a C library for multiband image merging using the Laplacian blending technique. It enables seamless blending of overlapping images, useful for applications such as panorama generation, image stitching, and exposure fusion. Only supports JPEGS for now.

Building

A helper script (build.sh) is included to streamline the build process for different platforms. Use this script to build or clean the project easily.

🔨 Build Instructions:

• Build for macOS:

  ./build.sh build macos

• Build for ios:

  ./build.sh build ios

Testing

To verify the functionality of NativeSticher, follow the instructions below based on your setup.

---

1. Testing with libturbojpeg (Direct Compilation)

If you have libturbojpeg installed, compile and run the test with the following command:

gcc-14 -O3 -mavx2 -mfma -I simde/ -pthread -fsanitize=address -g -o stitch \
-I../ -I/usr/local/include \
-L/usr/local/lib -lturbojpeg \
stitch.c ../blending.c ../jpeg.c ../image_operations.c ../utils.c && time ./stitch

2. Testing with Custom-Built NativeSticher Library

If you have manually built the NativeSticher library, use the following command to test it:

gcc-14 -pthread -fsanitize=address -g -o stitch \
-I../installs/native-stitcher/macos/x86_64/include \
-L../installs/native-stitcher/macos/x86_64/lib \
-Wl,-rpath,../installs/native-stitcher/macos/x86_64/lib \
-lNativeSticher stitch.c && ./stitch

The commands above assume a mac as working machine.
