C++ implementation of seam carving (content-aware resizing of images).
The implementation:
- uses index wrapping to compute energies at image boundaries.
- is parallelized using OpenMP (where applicable and beneficial) but not particularly optimized.
- currently only carves vertical seams, and, due to uint32 overflow, handles only images which are less than 22000 pixels in the height.
- takes (almost) any image file type as input, but only outputs PNG.
Usage:
./run.sh <input filename> <output filename> <num seams to carve>
To see an example, take pano.jpg[1] from images/,
carve 400 seams from it, and store the result in images/pano-out.png like so:
./run.sh images/pano.jpg images/pano-out.png 400
