This article provides an overview of a real-time, hybrid computational system for the violin, Windowless. The system uses a custom sensor glove, the alto.glove, to track the violinist’s movements and drive a panoply of unique digital sound processing effects. The author describes the operations of the system in terms of a broad notion of synthesis, consis-tency, microintervallic motions and molecular operations. A threefold approach combining dense sonic physics, “loose” computational procedures and high system responsiveness creates a rich and thick performative medium with a vapor-like, particulate level of textural and bitwise computational detail.

Enhancement Algorithm

According to the characteristics of infrared images, a contrast enhancement algorithm was presented. The principium of FPGA-based adaptive bidirectional plateau histogram equalization was given in this paper. The plateau value was obtained by finding local maximum and whole maximum in statistical histogram based on dimensional histogram statistic. Statistical histogram was modified by the plateau value and balanced in gray scale and gray spacing. Test data generated by single frame image, which was simulated by FPGA-based real-time adaptive bidirectional plateau histogram equalization. The simulation results indicates that the precept meet the requests well in both the image processing effects and processing speed

Digital Sound

The development of digital competencies of students is currently one of the main pedagogical tasks. The solution of this task is possible by paying attention to issues related to the skills of students to create their own digital content, for example, multimedia, combining various types of information (text, graphics, video and audio). The article provides a brief analysis of the content of teaching issues related to the study of digital sound processing technologies in a school informatics course. Taking into account the relevance of this issue, a thematic module "Digital Sound" is proposed, the content of which does not require binding to specific software. When  studying the module, the emphasis is on mastering specific technologies for processing sound information. The module can be implemented as an optional course for students in 7–9th grades and/or as an elective course for students in 10–11th grades. At the same time, particular blocks of the module can be used at various stages of teaching informatics at school

Automatically Tracking

Due to the increasing popularity of surveillance and security systems, the problem of automatically tracking a moving target by visual servoing has become a research topic deserving more investigation. Nonetheless, the success of tracking a moving target in real-time primarily depends on the performance of the motion detection techniques employed. This paper addresses visual tracking control of an unknown target that could be motional arbitrarily in the scene. A pan-tilt mechanism is used to gain the flexibility of tracking, and the so-called region-based matching method and motion energy method are modified and proposed in this study to detect a moving target based on the consecutive images acquired. A visual servo control scheme that adopts proportional control in the visual loop for reducing the servo lagging is proposed using output disturbance feedforward compensation. Experimental results show the superiority of the proposed method in achieving high system bandwidth and tracking accuracy.
