Automatic trimap generation and artifact reduction in alpha matte using unknown region detection

作者：

Highlights：

• An approach for automatic trimap generation for image matting is proposed.

• The trimaps generated by the proposed scheme can reduce artifacts in alpha mattes.

• Alpha mattes computed by our optimal trimaps are processed faster than when using trimaps from previous works.

• Performance of the proposed method is evaluated on two datasets.
