In this paper, an unsupervised global threshold technique, which is based on histogram analysis, is proposed. This technique analyzes the histogram. The histogram is partitioned in intensities at equal interval, and each interval assigned as single intensity. Then, differentiation is applied to get location of maxima in histogram. Depending on the locations of maxima, threshold is calculated to separate the two regions as change and no-change. The utilization of the differentiation improves t...

VANETs is an important part of wireless networking. Vehicular movement is unending expanding wherever on the planet and can cause horrible activity clog. The greater part of the signals till date include a settled green signal arrangement, so the green signal timing is done without considering emergency vehicles. In this way, emergency vehicles, for example, are stuck in congested driving conditions and postponed in achieving their goal can prompt loss of property and important lives. In this...

The current share of coal in India’s installed electricity generation of 343789 MW is about 57%. India produced 662.792 MT in 2016-17 with a projected output of 1 billion tonnes by 2020. The majority of it would be sourced from high capacity open cast mines. It needs large HEMMs that need rugged, strong and hence, durable haul roads. Haul road construction materials have not matched to the increasing capacities of heavy earth moving machineries. Conventional materials for construction of ha...

In this paper we investigate the application of local tetra patterns to the compressed domain camera zoom recognition problem. The primary aim is to separate the zooming frames from the non-zooming (panning, tilting) frames for which the block motion vector orientation information is modeled utilizing a 3× 3 neighborhood and local tetra patterns. These patterns are binarized followed by feature reduction using the concept of uniform patterns and finally fed to the C-SVM classifier for recogni...
