It is a hot topic to combine visual perception principles in video encoding. A fast algorithm for region of interest (ROI) detection based on human visual system (HVS) and coding information is proposed in this paper. Low-level coding information is employed as the characteristics of visual perception analysis in order to avoid a large amount of computation for visual perception characteristics...

The problem of change detection of time series with abrupt and smooth changes in the spectral characteristics is addressed. We first review the main characteristics of the discrete wavelet transform and the maximal overlap discrete wavelet transform. An algorithm for sequential change detection in time series is then reported based on the maximal overlap discrete wavelet transform and Bayesian ...

The vertebrate retina generates a stack of about a dozen different movies that represent the visual world as dynamic neural images or movies. The stack is embodied as separate strata that span the inner plexiform layer (IPL). At each stratum, ganglion cell dendrites reach up to read out inhibitory interactions between three different amacrine cell classes that shape bipolar-to-ganglion cell tra...

High dimension, redundancy attributes and high computing cost issues usually exist in the industrial Internet intrusion detection field. For solving these problems, the mutual information-based intrusion detection model for industrial Internet was proposed. Firstly, by using features selection method based on mutual information, the attributes set was reduced and traffic characteristics vector ...

background the importance of proper qualitative evaluation of eeg parameters during surgery has been recognized since many years. although none of the characteristics based on the frequency, entropy, and bi spectral characteristics have been regarded as a good predictor for detection of the depth of anesthesia alone. so it seems necessary to study multiple characteristics together. objectives i...

Because of high fire frequency and huge damage, the early fire detection is becoming more and more important. Due to the rapid development of image processing technology, video image in the application of detection technology has become more and more widely. Video based fire detection technology is becoming the focal point of research with its advantages of high intuitive, speed and anti-jammin...

To improve the recognition rate of dynamic target under complex background, this paper studied the target characteristics and recognition algorithm of moving target. According to the light intensity, target shape and motion characteristics, the calculation model of the target characteristics was established, the optical radiation characteristic and the detection performance of photoelectric det...

in recent years, based on the growing importance of clean energy in comparison with conventional energy production from fossil fuels, dg systems are gradually becoming more popular all over the world. these resources solve many problem of system. however, these resources create some other problems too. one of the most problem of dgs is unwanted islanding. this paper addresses reliable passive i...

wireless sensor networks (wsns) arebecoming increasingly popular, and very useful in militaryapplications and environmental monitoring. however,security is a major challenge for wsns because they areusually setup in unprotected environments. our goal in thisstudy is to simulate an intrusion detection system (ids)that monitors the wsn and report intrusions accurately andeffectively. we have thus...
