Energy efficiency in data collection and transmission is always a crucial factor in wireless sensor network (WSN). Unreliability in data transmission is very common for long range communications in WSNs. Factors like fading of channel, interference and radio irregularity further pose a big challenge on the design of energy efficient data transmission protocols in WSNs. Cooperative MIMO (Multiple Input...
This paper utilizes the characteristics of the Human Visual System (HVS) for obtaining better results in denoising color images corrupted by Gaussian noise. Implementation of the Contrast Sensitivity Function (CSF) of the HVS is done in each of the sub-bands in the wavelet domain. In this paper, an 11-weight Invariant Single Factor (ISF) system is proposed and implemented which outperforms the generally...
