A Fast and Robust Point Tracking Algorithm
We present an algorithm that efficiently tracks a predefined set of landmark points in a time sequence of images. The algorithm iteratively optimizes the correspondences between t...

An Efficient Mutual Information Optimizer for Multiresolution Image Registration
We propose a new optimizer in the context of multimodal image registration. The optimized criterion is the mutual information between the images to align. This criterion requires ...
