The work focuses on techniques for finding significant features in ionograms captured by the MARSIS instrument onboard the Mars Express spacecraft. Identification of these features helps in studying the ionosphere, magnetosphere and plasma surrounding Mars. Ionograms are 2D images with values represented in color. The goal of this work is to propose techniques to detect interesting curves (parametrically defined) in such images and to measure some more parameters of the found objects (like the repetition period of lines). During the research we managed to propose two methods very suitable for ionogram studies and we explored several other methods.

The main target of the Origamist application is to aid with creating origami diagram manuals. Recently, the most common methods for creating those manuals are drawing the steps in an image editor, or taking photographs of the folded steps and composing them together (again in an image editor). What Origamist brings is a new alternative to these methods. The manual's author gets the possibility to transfer the sequence of paper folds the manual consists of to the Origamist application, which is able to export several types of output - the most favourite (among origami folders) PDF manuals, but also image manuals (as PNG or SVG), and even as an animation of the folding process. There is also the added value to translate the descriptions of the steps to several languages.
