Odpovědná osoba: Kotera
Two parts of the seminar will be:
1) Decomposition of Space-Variant Blur in Image Deconvolution
Space-variant convolution blur model will be presented and the important difference between PSF a convolution filter will be highlighted. Two different decompositions of the model lead to two methods for deconvolution. The numerical behavior of different methods will be presented on mostly syntetic exmeriments.
2) Total-Variation Demosaicing
Simple approach to the demosaicing task possible to formulate as a total-variation minimization will be described.
