Traffic noise pollution is a growing problem that highly affects the health of people. To cope with this problem one has to regulate traffic or construct noise barriers. In order to implement effective measures against traffic noise the information about its distribution – noise maps is imperative. This paper presents our work in creating a noise calculator software package implementation that ...

More and more robotic applications are equipping robots with microphones to improve the sensory information available to them. However, in most applications the auditory task is very low-level, only processing data and providing auditory event information to higher-level navigation routines. If the robot, and therefore the microphone, ends up in a bad acoustic location, then the results from th...

Removal of noise and restoration images has been one the most interesting topics in field image processing past few years. Existing filter-based methods can remove noise; however, they cannot preserve quality information such as lines edges. In this article, various classifiers spatial filters are combined to achieve desirable restoration. Meanwhile, time adaptive self-organizing map (TASOM) cl...

In order to study the ability of coupled neural oscillators to synchronize in the presence of intrinsic as opposed to synaptic noise, we constructed hybrid circuits consisting of one biological and one computational model neuron with reciprocal synaptic inhibition using the dynamic clamp. Uncoupled, both neurons fired periodic trains of action potentials. Most coupled circuits exhibited qualita...

Noise power spectral density (PSD) estimation is a crucial part of speech enhancement system due to its contributory effect on the quality of the noise reduced speech. A novel estimation method for color noise PSD on the basis of an assumption of generalized Gamma distribution and maximum a posteriori (MAP) criterion is proposed. In the experiment, generalized Gamma PDF which is a natural exten...

The intriguing characteristics of chaotic maps have prompted researchers to use these sequences in watermarking systems to good effect. In this paper we aim to use a tent map to encrypt the binary logo to achieve a like-noise signal. This approach makes extraction of the watermark signal by potential attacker very hard. Embedding locations are selected based on certain principles. Experimental ...
