Text area detection in digital documents images using textural features
(Springer, 2007)
In this paper we propose a new texture-based method for extraction of text areas in a complex document image. Gabor filter motivated by the multi-channel filtering approach of Human Visual System (HVS) has been employed ...
Effect of channel estimation errors on the performance of space time coded systems with antenna selection
(2007)
This paper presents the effects of channel estimation errors on the performance, especially diversity gain, of space-time coded systems with antenna selection. We consider maximum signal to noise ratio as the antenna ...
Analytical approaches for the amplitude and frequency computations in the astable cellular neural networks with opposite sign templates
(2007)
In this paper, by using surface fitting methods, analytical approaches for amplitudes and frequencies of the x1,2(t) "States" in a simple dynamical neural network called "Cellular Neural Network with Opposite Sign Templates" ...
