Object recognition and texture identification are the two main application of sonar image processing. It consists of 3 main steps such as image segmentation, object recognition and pattern identification. Before all these steps, some of the preprocessing procedure are included such as filtering of noise, edge detection etc. Many edge detection operators are available and also a mathematical modeling...
Image Denoising nowadays is a great Challenge in the field of image processing. Since Discrete wavelet transform (DWT) is one of the powerful and perspective approaches in the area of image de noising. But fixing an optimal threshold is the key factor to determine the performance of denoising algorithm using (DWT). The optimal threshold can be estimated from the image statistics for getting better...
The present and the past work of the sonar image enhancement techniques are reviewed in this paper and we also discussed about the steps involved for object detection. In digital image reconstruction image fusion plays a major role of preprocessing. Image fusion will integrates the relevant information of same scene from multiple images with same dimension. The resultant image should be better quality...
Mobile Wireless Sensor Networks (MWSNs) are a current encouraged technology which is used to help many civilian, military and industrial services. Energy saving is the critical issue while designing the wireless sensor networks. In order to enhance the network life time there are many routing protocols have been developed. One of these is clustering based in which network is partitioned into small...
In Wireless sensor networks, existing energy efficient routing algorithms assumed that the sensor nodes are stationary. Some of the applications in WSN must combine with both mobile sensor nodes and fixed sensor nodes in the same networks. When mobility is functioned there should be performance degradation. Because these nodes are equipped with a lesser amount of memory, restricted battery power,...
Energy is very essential for sustenance of life on this earth, without energy, life will come to a stands still. Perhaps after food, energy is the most important component for economic development of a country and for improving the quality of life of the people. Therefore, one of the most important tasks of the planning process is to ensure sharp increase in production of energy. In fact, the per...
