Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| add foreground/background click hints at test time (ablation) | Hints-TrainTest · DIM test | SAD: 2.17 -> 1.68 | Helped |
| train with simulated click hints (ablation) | DIM matting network · DIM test | SAD: 2.26 -> 2.17 | Helped |

| use the proposed click-based method instead of LF-Matting | DIM matting · DIM test | SAD: 3.47 -> 1.68 | Helped |
| use the proposed method instead of GCA-Matting | DIM matting · DIM test | Grad: 8.97 -> 7.57 | Helped |
| use the proposed method instead of GCA-Matting | DIM matting · DIM test | SAD: 1.50 -> 1.68 | Hurt |
| remove local refinement (ablation) | uncertainty-guided matting · DIM transition regions | SAD: 8.34 -> 8.69 | Hurt |
| replace global refinement with 8 uncertainty-guided local patches (ablation) | matting refinement · DIM transition regions | SAD: 8.57 -> 8.53 | Helped |
| increase uncertainty-guided local refinement from 4 to 32 patches (ablation) | matting refinement · DIM transition regions | SAD: 8.60 -> 8.29 | Helped |
