Abstract :
In this paper, an adaptive neural network architecture is proposed for efficient video object segmentation and tracking of stereoscopic sequences. The scheme includes (a) a retraining algorithm for adapting network weights to current conditions, (b) a semantically meaningful object extraction module for creating a retraining set and (c) a decision mechanism, which detects the time instances that a new network retraining is required. The retraining algorithm optimally adapts network weights by exploiting information of the current condition with a minimal deviation of the network weights. Description of the current conditions is provided by a segmentation fusion scheme, which appropriately combines color and depth information.
