In present time due to increase in number of kidnapping and road accident cases, parents always worry about their children. This paper recommends a SMS based solution which assists parents to track their children location in real time. To track the location GPS module is used and to identify the identity of the child a RFID card is used which is in built in the system. Whenever a child boards a bus,...
The Normalized Difference Vegetation Index (NDVI) is one of the most widely used numerical indicator that uses the visible (VIS) and near-infrared bands (NIR) of the electromagnetic spectrum, and is utilized to analyze remote sensing images and assess whether the target contains live green vegetation or not. This paper analyses the utility of NDVI for mapping the land cover characteristics over Tirupati...
In this paper, the gamma corrected adaptive knee transformation, proposed by Monobe et al. is reviewed and improved by exploiting two-dimensional single level Beta wavelet filter for subband decomposition of the low contrast satellite images. For this purpose, the input image is initially decomposed into its subband images such as low-low (LL), low-high (LH), high-low (HL), and high-high (HH)). Then,...
Satellite images are mostly degraded due to the inaccuracy or limitations of the transmission and storage devices. Removal of noise from satellite images are still a challenging task for many researchers. The conventional image denoising algorithms mostly use wavelet transform. The main limitation of wavelet transform is that it can capture only limited information along different directions. Hence...
This paper provides a comprehensive survey focused on applicability of MIMO and Multicarrier systems to satellite communication. The significant research achievements in the area of Multiple antenna and multicarrier technology can be successfully used in satellite communication similar to terrestrial communication. A detailed review of MIMO and OFDM based techniques for satellite communication is...
Image fusion taking into account the wavelet and fourier change grades rich multispectral points of importance yet provides fewer spatial subtle elements from basis images. Wavelet performs well at direct elements yet not at non-straight cutoffs since Wavelets don't utilize the geometric assets of assemblies. Curvelet overwhelmed such challenges in highlight representation. A novel Image fusion principle...
This paper presents, the tracking of IRNSS satellites over Indian geo-graphical boundary from the user position (SET-Jain University). The work is also focused on monitoring the IRNSS and hybrid (GPS+IRNSS) satellite constellation with the availability across the hemispherical region. The objective is extended to analyze the visibility gap for IRNSS and hybrid navigational satellites to show the significance...
This paper proposes a satellite receiver filter design using FIR digital filtering technique. We present various design methods like windowing, least squares and equiripple for satellite burst demodulator application and compare their performance. Various designs of FIR filter are compared from the view point of hardware complexity, frequency response characteristics and implementation strategies...
This paper deals about the availability, visibility and Position accuracies of Indian Regional Navigation Satellites System (IRNSS). The position accuracies has been observed and plotted with respect to the standard time. The IRNSS — user receiver placed at school of engineering and technology, Bangalore. Indian space research organization has launched three Indian regional navigation satellites (IRNSS-1A,...
Normally images obtained from satellites are of low-contrast type which hides major information carried by the image. Hence, image restoration is necessary in the image processing domain to extract all the information present in the images. The low contrast satellite image restoration based on adaptive histogram equalization combined with Discrete Cosine Transform (DCT) and Discrete Wavelet Transform...
