Endovascular surgery is becoming a widespread procedure to treat cardiovascular diseases (CVDs) such as abdominal aortic aneurysm and peripheral artery disease. The guide-wire is a crucial surgical instrument inserted into vessels to offer guidance to physicians during the surgery.

In this paper, we show how to reconstruct both 3D shape and 2D texture of a class of surfaces from a single perspective image. We consider the so-called the generalized cylindrical surfaces that are wrapped with low-rank textures. They can be used to model most curved building facades in urban areas or deformed book pages scanned for text recognition. Our method leverages on the recent new techniques...
Super Sketchpad(SSP) is a domestic software of dynamic mapping, providing powerful and rich functionalities for teaching and learning of geometry discipline in primary shools. Allusion to subject characteristics, this paper presents SPUI, a scheme for developing pen-based user interface. SPUI provides a more natural input interface for SSP. The SPUI gives a detailed description to the system architecture...
