Orthogonal wall correction for visual motion estimation
— A good motion model is a prerequisite for many approaches to simultaneous localization and mapping. Without an absolute reference, it is however difficult to prevent drift whe...

Endocardial Tracking in Contrast Echocardiography Using Optical Flow
Myocardial Contrast Echocardiography (MCE) is a recent technique that allows to measure regional perfusion in the cardiac wall. Segmentation of MCE sequences would allow simultaneo...

Real-Time Tissue Tracking with B-Mode Ultrasound Using Speckle and Visual Servoing
We present a method for real-time tracking of moving soft tissue with B-mode ultrasound (US). The method makes use of the speckle information contained in the US images to estimate...

Extraction of Outcrop Points from Visual Hulls for Motion Estimation
In this article, we discuss 3D shape reconstruction of an object in a rigid motion with the volume intersection method. When the object moves rigidly, the cameras change their rel...
