Akima spline
open-in-new
<p>In applied mathematics, an Akima spline is a type of non-smoothing <a href="/facts/Spline_(mathematics)/yafkQtqp">spline</a> that gives good fits to curves where the second derivative is rapidly varying. The Akima spline was published by Hiroshi Akima in 1970 from Akima's pursuit of a <a href="/facts/Spline_(mathematics)/yafkQtqp">cubic spline</a> curve that would appear more natural and smooth, akin to an intuitively hand-drawn curve. The Akima spline has become the algorithm of choice for several computer graphics applications. Its advantage over the cubic spline curve is its stability with respect to outliers. </p>
