PC control via eyes
Neuwirth, Tomáš ; Číp, Pavel (referee) ; Horák, Karel (advisor)
The presented master thesis deals with the evaluation of the position of the iris compared with surroundings of the eye. This technique is supposed to be use for computer control. The created software works in real-time mode, the pictures are taken with an ordinary webcam. The first part of the work presents basic algorithms used in computer vision for edit of images. The following part is focused on abilities of methods to find the face, eyes and to detect the iris. The detection and the subsequent separation of the face is based on the recognition of skin colour in the YCbCr color space. The position of eye is then searched in the face by Haar-like features. The darkest part of the eye is found by horizontal projection from surroundings and the seed point is started from this place. From the area which is filled by the seed method (Flood Fill) and which shows the iris, the cursor movement is controlled by obtained x and y position.

Real-time Crane Control via PC
Arm, J.
In this paper, creation of SCADA system, which controls and monitors model of gantry crane in real time, is described. This crane will be controlled via process station communicating with PC via Modbus TCP protocol. Moreover, HTTP server will be created to monitor crane state over intranet. On this work, the difference between real-time and fast execution will be described and it will be shown on the built system that the fast execution system can behave like a real-time system under specific conditions.
