Traditional image matting algorithms rely heavily on low-level features, such as color information. Sampling-based [3, 4, 20, 21] or propagation-based [1, 9] methods tend to have bad matting results in the case of more complex backgrounds.With the tremendous progress in deep learning, many Convolutional Neural …
WebAlthough some learning-based matting algorithms try to address the issues pertaining to the coarse trimap directly by data fitting, their generalisation performance is unstable due to the limitations implicit in specific scenes [8, 9]. Therefore, in most matting algorithms, the coarse trimap is pre-processed prior to its further use. Web1 aug. 2024 · However, the algorithm in [5] had higher calculation complexity as the additional using of the soft matting algorithm. He [7] further proposed the guided image filter, which could be used to refine the atmospheric transmittance map. From the experimental results of [5] and [7], we can see that the algorithm in [5] ...
