Question

Advantage and disadvantage of homogeneous coordinate

Answer 1

Homogeneous coordinates are used extensively in computer vision and graphics because they allow common operations such as translation, rotation, scaling and perspective projection to be implemented as matrix operations.

Answer 2

Homogeneous coordinates are used extensively in computer vision and graphics because they allow common operations such as translation, rotation, scaling and perspective projection to be implemented as matrix operations.Advantages of homogeneous coordinates An important consequence of homogeneous coordinates is that we can represent several im- portant classes of transformation (linear, a ffi ne, projective) in a single framework - multipli- cation by a 3 × 3 matrix. ...
