Determining ellipses from low-resolution images with a comprehensive image formation model
Wojciech Chojnacki, Zygmunt L. Szpak
When determining the parameters of a parametric planar shape based on a single low-resolution image, common estimation paradigms lead to inaccurate parameter estimates. The reason…
Full explicit consistency constraints in uncalibrated multiple homography estimation
Wojciech Chojnacki, Zygmunt L. Szpak
We reveal a complete set of constraints that need to be imposed on a set of 3-by-3 matrices to ensure that the matrices represent genuine homographies associated with multiple plan…
Evolutionary Image Composition Using Feature Covariance Matrices
Aneta Neumann, Zygmunt L. Szpak, Wojciech Chojnacki +1
Evolutionary algorithms have recently been used to create a wide range of artistic work. In this paper, we propose a new approach for the composition of new images from existing on…
On cosine families close to scalar cosine families
Wojciech Chojnacki
We prove that if two normed-algebra-valued cosine families indexed by a single Abelian group, of which one is bounded and comprised solely of scalar elements of the underlying alge…
