Виртуално окачване на автономни транспротни средства

Венков, Пенчо Георгиев; Venkov, Pencho Georgiev, (2004)
This paper describes a system for virtual attachment of autonomous vehicles.. The system is aimed to guide one or more unmanned vehicles — followers without a mechanical attachment to the guiding vehicle. A multisensors system, mounted on the follower vehicle, is used to measure the linear and the angular velocity of the guiding vehicle, marked by a colored lighting sign-board. The multisensors system includes a colored RGB computer vision, a long range radar for vehicles and a short range ultrasonic locator. The system measures the parameters of the guiding vehicle's trajectory in me time or a TV frame, e.g. 40 ins.
Алгоритми и програмно осигуряване за обработка на цветни изображения в реално време

Венков, Пенчо Георгиев; Делийски, Радослав Цветков; Иванов, Славян; Venkov, Pencho Georgiev; Deliyska, Radoslav Tsvetkov; Ivanov, Slavyan, (2004)
The paper describes algorithms and software for color detection and analysis of patterns in TV camera frame time. The color components are normalized with the purpose to eliminate the influence of scene's illumination. In the first algorithm 32 base colors are defined into the 3D color space by pairs of thresholds and combined logical criteria is used for pixels' classification. in the second algorithm the color zones are defined by clusters in a normalized r(g)b color space in the stage of education, while the classification is made with criteria for similarity between a color pixel and the clusers.
Програмно осигуряване на система за техническо зрение за следене на мобилни обекти

Делийски, Радослав Цветков; Венков, Пенчо Георгиев; Deliyski, Radoslav Tsvetkov; v, Pencho Georgiev, (2004)
The paper describes the software module "Image Analizator", which determines the distance and location between guiding and unmanned folowing vehicles in TV camera's frame time. Problems associated with processing, analyzing and recognition of targes in color image are soIved, as well as measurement of geometric parameters, which described the movemenst of the guiding transport means. The report describes results from experimental investigations that software made with a real moving target
Статистически анализ на функционални изображения с магнитен резонанс

Иванова, Полина Стоева; Венков, Пенчо Георгиев; Ivanova, Polina Stoeva; Venkov, Pencho Georgiev, (2004)
The paper describes a statistical method for localization of the brain activity, based on the hypothesis that functional images of magnetic resonance (WO contain an useful but noisy information for the excitation area in the brain. The aim of this analysis is to construct an allocation map, describing the zones of neuronal activity, related with physiological paradigms of external stimulation of the brain. We use parametrical methods to verify some hypothesis for the degree of excitation of every voxelof the brain, based on the distribution of the grey levels of pixels in a sequence of PMR1 images.
