The main aim of the project is to develop a 2D and 3D geometrical transformation training program. The goal of research is to analyse geometrical transformation practical usage. The existing geometrical transformation systems and new developed system are reviewed. The object oriented design was used to develop a system. 2D and 3D geometrical transformation viewing, task generating and its solving training system was developed.

The goal was to verify in which measure the use of Dynamic Geometry Software Cabri Géomètre II contributed to articulate and give meaning to the concepts of translations, reflection and rotation. The Tool-Object Dialetic, in accordance with Régine Douady, were used on the activities development. The methodology followed some steps in the Didactical Engineering. The subjects were the high school students in a public school in the city of Santos. We concluded from the students productions that the introduction of the frieze patterns in the didactical sequence helped the articulation among the different geometrical transformation contributing to a high quality step forward in the purpose shown in relation to the mainly concepts of them. / O trabalho pretende fazer um estudo de algumas transformações geométricas no plano Euclidiano a partir da dimensão artística dos frisos (faixas). O objetivo visado foi verificar em que medida o uso dos frisos com a ajuda do software de geometria dinâmica Cabri-Géomètre-II contribui para articular e dar significado aos conceitos de translação, simetria axial e simetria central. A Dialética Ferramenta-Objeto de Régine Douady foi utilizada na concepção das atividades. A metodologia utilizada seguiu algumas etapas da engenharia didática. Os sujeitos foram alunos de 1º ano do Ensino Médio de uma escola pública de Santos. Pudemos constatar nas análises feitas a partir das produções dos alunos que a introdução dos frisos na seqüência didática, favoreceu a articulação entre as diferentes transformações geométricas contribuindo dessa forma para um salto qualitativo nas justificativas apresentadas em relação aos principais conceitos das transformações.

Registration of medical images is technique, which is developing with new hybrid diagnostic imaging systems. Nowadays is a trend in image registration focused on monomodality and multimodality images registration. The first part of this master’s thesis is intent on present basic information about image registration. Concretely is intending on image transformation, interpolation, criteria function and at optimalization. Further part present realized Optical Flow technique and used “Demon” algorithm for image registration. The next part is focused on presentation of program solution and GUI. In the last section of this master’s thesis is verifying of created program on usual images and real CT images.
