Tensor-Based Filter Design using Kernel Ridge Regression
Tensor-based approaches to visual object detection can drastically reduce the number of parameters in the training process. Compared to their vector-based counterparts, tensor methods therefore train faster, better manage noisy or corrupted training samples, and are less prone to over-fitting. In this paper, we show how to incorporate the kernel trick into tensor-based filter design. Dealing with object detection in cluttered natural environments, the method is shown to cope with substantially varying training data and a cascade of only two kernel tensor-filters is demonstrated to provide very reliable results.
