For the next 3 questions, let us assume that we have a sensor collecting a 3D point cloud in an environment. From this data, we need to design an algorithm to identify generic infinite cylinders: the main axis of the cylinder and its radius are unknown. However, we do not try to recover the length of the cylinder (it is infinite). Note that a generic cylinder is completely constrained with 4 points.

Which of the following is a heterotroph?

What are the parameters influencing the required number of iteration in RANSAC? You are not required to write the formulas linking this parameters to the number of iteration, just list the parameters.

Using a logarithm and a change of variable, show that this problem can be simplified to fitting a 2D parabola of the form:

Using this result, propose a RANSAC strategy to robustly estimate (a, b, c, d) and extract the inlier points from this model.

Seven bones form the top part of the spinal column and are often lightly massaged in a facial service are known as the:

Having extracted the inliers, explain how regression can be used to compute the least-square fit of (a, b, c, d) to the data. This question can be answered independently of the previous ones.
