In mathematics, the tangent line to a curve at a point is a straight line that touches the curve at this point only. The tangent line can provide valuable insights into the properties of the curve, ...

To construct the tangent to a curve at a certain point A, you draw a line that follows the general direction of the curve at that point. An example of this can be seen below. Once the tangent is found ...

Abstract: This paper presents a robust and accurate approach for the rigid registration of pre-operative and intraoperative point sets in image-guided surgery (IGS). Three challenges are identified in ...
