Reflection Detection and Removal From Image Sequences
 Hodaň, Tomáš ; Juránková, Markéta (oponent) ; Herout, Adam (vedoucí práce)
The aim of the Master's thesis was to study existing methods for detection and removal of specular reflection from image sequences, to find their limitations and to suggest possibilities of their improvements. Particularly, an attention was paid to planar specular (i.e. mirror-like) surfaces whose appearance can be modeled by linear superposition of reflection and transmission layer. We reviewed the existing motion-based methods and described their common degenerate case in terms of disability to correctly recover regions with low frequency in the direction of camera motion. A new method designed to eliminate this degenerate case was suggested. Its main contribution is a new approach to layer gradients estimation where a special treatment of the gradients forming edges of the problematic regions is taken. We focused also on the following color recovery process and described an alternative approach to the traditional quadratic programming.
