Fig. 13 showcases our model’s performance in challenging scenarios, particularly in accurately rendering hair regions. Our framework consistently outperforms MGM⋆ in detail preservation, especially in complex instance interactions. In comparison with InstMatt, our model exhibits superior instance separation and detail accuracy in ambiguous regions.
\ Fig. 14 and Fig. 15 illustrate the performance of our model and previous works in extreme cases involving multiple instances. While MGM⋆ struggles with noise and accuracy in dense instance scenarios, our model maintains high precision. InstMatt, without additional training data, shows limitations in these complex settings.
\ The robustness of our mask-guided approach is further demonstrated in Fig. 16. Here, we highlight the challenges faced by MGM variants and SparseMat in predicting missing parts in mask inputs, which our model addresses. However, it is important to note that our model is not designed as a human instance segmentation network. As shown in Fig. 17, our framework adheres to the input guidance, ensuring precise alpha matte prediction even with multiple instances in the same mask.
\ Lastly, Fig. 12 and Fig. 11 emphasize our model’s generalization capabilities. The model accurately extracts both human subjects and other objects from backgrounds, showcasing its versatility across various scenarios and object types.
\ All examples are Internet images without ground-truth and the mask from r101fpn400e are used as the guidance.
