English title
Non-Linear Filtering of Large 3D Images

This bachelor thesis deals with design and effective implementation of nonlinear filters, bilateral filter and non-local means filter, for denoising 3D image data. The implemented filters are optimized by various techniques such as parallel processing, integral image, sampling etc. This thesis project includes cross-platform solution of these filters in C\# language and two demonstration applications -- a GUI application for Windows and a cross-platform console application -- demonstrating the use of the library. The performance and output of implemented filters were tested and compared against open source reference filters (Itk, scikit-image), with the 3D bilateral filter implementation being up to $30×$ faster than the available     implementation of the Itk filter and the implementation of the 3D non-local means filter is approximately $2×$ faster than the scikit-image implementation
