The paper presents technical aspects related to the video computer analysis of people movement in the sales rooms. Automatic generation of the people density maps (also referred to as the “heat maps”) is helpful for the analysis of customers' and employees' behavior in sale and office rooms advertising effectiveness research or tracking movements. Generation of the density maps was realized with the...
N2R structures are a subset of generalized Petersen graphs and a potentially good option to be used for implementing degree three networks. The previous works on these structures verify that N2R are better than other degree three regular topologies such as double rings or honeycomb in terms of path distances. The cost of this good performance is a more complex and non-planar interconnection configuration;...
This paper presents results of our research on automatic telephone call speaker recognition. A significant improvement of recognition quality can be observed if we use the knowledge on how the original speech was coded, e.g., using GSM or PCM telephone standard. On this basis we can improve the quality of the speaker models. In order to realize such a speech analyzer we propose to analyze the mean...
In this paper three illustrative full-custom baseband chips together with the respective testing methods and measuring setups are presented. The described circuits contain (among other elements) discrete-time switched-capacitor finite impulse response (SC FIR) filters. These filters operating in the baseband frequency range exhibit many important advantages such as low-power and high precision. As...
In this paper an algorithm for detection of endpoints of isolated words, which is a part of the automatic speech recognition (ASR) system, is presented. Our algorithm is based on the Legendre (slope) transformation. In order to analyze an influence of the proposed algorithm on the recognition effectiveness, a set of 10 Polish steering words was tested in two characteristic cases: recognition of original...
In this paper a concept of using the Bluetooth wireless telecommunication system for the construction of devices supporting blind, hearing impaired, and speech handicapped people is presented. People of the third considered class can be mute from infancy or their speech organs can be disordered after larynx surgical operations. Various possibilities of the Bluetooth technology applications in supporting...
