Closed Form Matting

Customized implementation of the closed form matting alogrithm which is proposed by A. Levin。This is an alogrithm for image matting by giving certain constraints, i.e. trimap or scribble.

Usage

for trimap

python main.py --mode=matting --image=/path/to/your_image --trimap=/path/to/your_trimap_image --output_dir=/path/to/output

for scribble

python main.py --mode=matting --image=/path/to/your_image --trimap=/path/to/your_scribble_image --output_dir=/path/to/output

and in order to guide scribble, you may need smallest eigenvector of Laplacian

python main.py --mode=eigen --image=/path/to/your_image --output_dir=/path/to/output

Result

From left to right, [image, trimap/scribble, alpha, matting]
