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…
