Such models are preferable since they can be identified from the vision data without any a-priori knowledge.

Bootstrap Initialization of Nonparametric Texture Models for Trackingion is feasible in both domains. We find that (1) independence assumptions in the learning process can be violated to a significant degree, if enough data is taken; (2) there are both domain-independent and domain-specific means to mitigate learning bias; and (3) repeated bootstrapping does not necessarily result in increasingly better models.作者: 妨礙 時間: 2025-3-25 22:39 作者: Folklore 時間: 2025-3-26 00:14 作者: 豐滿中國 時間: 2025-3-26 06:24 作者: BOOR 時間: 2025-3-26 10:00
