    Continuous processing of images through user sketched functional blocks
    (1988) Kaya, Aydın
    An object oriented user interface is developed for interacting with and processing images. The software prepared for this purpose includes image processing functions as well as user friendly interaction tools both of a lower level such as menus, panels, windows and a higher level such as a schematics. The lower level utilities provide direct interface with the available image processing functions. At the higher level, the nodes of the schematics serve as image processing function instantiations and the arcs are the paths through which processed images flow. By constructing such a schematics, a complex set of operations can be applied to images continuously.

    Texture mapping on geometrical models
    (1989) Açıkgöz, Oktay Aydın
    The contribution of the visual effects of textures is an important aspect in generating images of real objects. Texture mapping is a very successful technique in this respect. Texture mapping can be subdivided into two fundamental topics; the geometric mapping and the filtering. The texture mapping system developed in this study is adaptable to different types of geometric models. Superqueadric, Bezier or b-spline surfaces can be mapped with textures. The geometric modeling and the texture synthesis subsystems were also implemented for this purpose. The system works in an interactive manner, the user describes the geometric model and the texture and gets the result in a reasonable amount of time. The speed and the usability of the system by a naive user are the keypoints of implementation.
