Query: Chord Angle Deviation using Tangent (CADT), an Efficient and Robust
  Contour-based Corner Detector   Detection of corner is the most essential process in a large number of
computer vision and image processing applications. We have mentioned a number
of popular contour-based corner detectors in our paper. Among all these
detectors chord to triangular arm angle (CTAA) has been demonstrated as the
most dominant corner detector in terms of average repeatability. We introduce a
new effective method to calculate the value of curvature in this paper. By
demonstrating experimental results, our proposed technique outperforms CTAA and
other detectors mentioned in this paper. The results exhibit that our proposed
method is simple yet efficient at finding out corners more accurately and
reliably.
