# Seam Carving

A native C++ implementation of seam carving as described by Avidan et al. in [Seam carving for

content-aware image resizing](https://doi.org/10.1145/1275808.1276390). Learn more about seam carving from [this YouTube video](https://www.youtube.com/embed/6NcIJXTlugc).

## Getting Started

The seam carving library can be built using CMake. The available targets are:

- `seam_carving` - builds the dylib

- `demo` - runs the demo at `./demo.cpp`

- `carver_unit/energy_unit` - runs the unit tests at `tests/unit/[carver/energy].test.cpp` respectively

### Running the demo

1. Configure the CMake project. The code sample below uses Ninja as the generator. There are presets in `CMakePresets.json`

available to use. 

2. Build the `demo` target.

3. Run the demo target with a path to an image (sample images are provided in `samples/`), and the target size

```

# step 1 - from the root folder of the repo

cmake -B {PATH_TO_BUILD_DIR} -S {PATH_TO_REPO_ROOT} -G Ninja --preset default

# step 2

cmake --build {PATH_TO_BUILD_DIR} --target demo

# step 3

./demo {PATH_TO_IMG} {TARGET COLS} {TARGET ROWS}

```

## Seam Carving Shell (SCS)

The Seam Carving Shell (SCS) is undergoing major reconstruction and is not supported in v2.0.0.
