WebWe propose a method for creating a matte – the per-pixel foreground color and alpha – of a person by taking photos or videos in an everyday setting with a handheld camera. Most existing matting methods require a green screen background or a manually created trimap to produce a good matte. Automatic, trimap-free methods are appearing, but ... WebJun 20, 2024 · IamAlpha uses trimap adaptation as an auxiliary task to adapt and fix the input trimap errors. For trimap-based methods, the generation of trimap requires user interaction, making it not only non-real-time but also tricky to video matting. 2.2.2 Trimap-free matting. Recently, many methods have focused on predicting alpha matte without …

Web2.2 Trimap-free Matting methods. Recently, some trimap-free matting approaches have emerged. Some of them propose to train on large-scale dataset to completely get rid of trimap. Zhang et al. [20] use two decoder branches to predict foreground and background classification respectively and then fuse them together. Its input is only an RGB image. WebNov 25, 2024 · Second, for most of the existing trimap-free models, the learning of semantic mining often stems from upstream tasks such as segmentation. However, they may fail to identify the complete and meaningful foregrounds when such foregrounds are semantically ambiguous, rare, or spatially sparse, e.g. the cobweb in Row 1 of Figure 1.Although … WebMODNet is a light-weight matting objective decomposition network that can process portrait matting from a single input image in real time.
