Abstract
této diplomové práci je navržen postup 3D rekonstrukce šedotónových obrazů nanovlákenných struktur získaných z elektronového rastrovacího mikroskopu (SEM). 3D rekonstrukce tvaru vlákna je založena na aproximaci vlákna koulemi, které jsou v literatuře známé pod pojmem metabally. Techniky obrazové analýzy jsou využity pro generování polohy a velikosti jednotlivých metaballů. Vlákno je v každém bodě osy vlákna aproximováno metaballem. Metoda je testována jednak na sadě simulovaných obrazů, tak na sadě reálných obrazů nanovlákenných struktur a je získána informace o objemu.
In this thesis is proposed 3D reconstruction process of grayscale images nanofiber structures obtained from scanning electron microscope (SEM). 3D reconstruction of the shape of the fiber is based on an approximation of the fiber by balls which are known in the literature as metaballs. Image analysis techniques are used to generate position and size of each metaballs. Metaball approximattion of each pixel of the fiber axis is achieved 3D reconstruction fibrous structure. The method is tested, first on a set of simulated images and on a set of real images nanofiber structures is obtained and information about the volume.
