Converts points from homogeneous to Euclidean space

dst = cv.convertPointsFromHomogeneous(src)

Input

• src Input vector of N-dimensional points (3D/4D points). Mx3/Mx1x3/1xMx3 or Mx4/Mx1x4/1xMx4 numeric array, or cell-array of 3/4-element vectors in the form: {[x,y,z], [x,y,z], ...} or {[x,y,z,w], [x,y,z,w], ...}. Supports floating-point types.

Output

• dst Output vector of (N-1)-dimensional points (2D/3D points). Mx2/Mx1x2 or Mx3/Mx1x3 numeric array, or cell-array of 2/3-elements vectors, respectively matching the input shape.

The function converts points homogeneous to Euclidean space using perspective projection. That is, each point (x1, x2, ..., x(n-1), xn) is converted to (x1/xn, x2/xn, ..., x(n-1)/xn). When xn=0, the output point coordinates will be (0,0,0,...).
