Find the parametric representation for the part of the ellipsoid {eq}9x^2 + 4y^2 + z^2 =1 {/eq} that lies above xy-plane. Spherical Coordinates: Spherical coordinates are one of the three most important coordinates that exist in this space. The r...
The algorithm is based on a parametric representation of the ellipse. It is particularly inexpensive in terms of the amount of computation required. Only a few integer shifts, additions, and subtractions are needed to generate each point鈥攚ithout compromising accuracy. Defining an ellipse in ...

(unseen) frames of all videos, we specified video-wise cropping values in the DeepLabCut configuration file that corresponded to a square around the eye. The pupil size (exposed eye area) was computed as the area of an ellipse fitted to the detected pupil (exposed eye) points. If two or ...
This paper tries to answer the other half of the question: What is the set of images of an object under all viewing directions? A novel image representation is proposed, which transforms any n-pixel image of a 3D object to a vector in a 2n-dimensional pose space. In such a pose space...
First, unlike the classical frameworks on UGVs formation tracking, for which only particular shapes are handled (e.g. circle, square, ellipse), we propose a UGVs deployment-controller ensuring to reach free-formation shapes. The key feature is in using the estimated implicit representation of ...
