+Mandatory arguments: 
+
+- `-s FILE`: source image
+- `-o FILE`: output image
+
+Options: 
+- `-m FILE`: the mask. RGB image, of the same size than the source, red pixel are those to be removed, the green ones must be kept. 
+- `-n NUMBER`: number of seams to compute or remove (default 0)
+- `--show-seams`: do not carve the image, only outputs the energy and the relevant seams
+- `-f FUNCTION NAME`: the energy function to use, see the [beginning of the source file to see the available functions](src/seam-carving.cpp)
+- `-u`: when a mask is provided and no seam number is provided, remove seams until the zone to remove has disappeared.
