Webof the gradients of the edge indicator along the boundary are close to zero. However, the conventional active contours, such as [4], considers only the normal component of the gradient of the edge indicator. The curve evolution based only on the normal component often converges at the places where the tangential component is still significant. WebFor the curve y = f(x), you can find the equation of the normal at the point (a, f(a)) using Exam Tip The formulae above are not in the Edexcel exam formulae booklet, but if you understand what tangents and normals are, then the formulae follow from the equation of a straight line combined with parallel and perpendicular gradients (see Worked ...
