Article Info ABSTRACT Over the years, audio signal processing has grown significantly in terms of signal analysis and classification. There have been several proven evidences that it can be used to solve many issues related to environmental monitoring applications, especially in wildlife management and conservation-related projects. Since birds are...
Article
This paper discusses four heart sound segmentation (HSS) methods: Wavelet transform, Fractal decomposition, Hilbert Transform, and Shannon Energy Envelogram, in order to identify the different cardiac sounds. Many research studies related to heart signal analysis, have adopted these methods to give high heart sound segmentation results, especially,...
Chapter
As the drivers approach the signalized intersection, the drivers will face the dilemma of choosing to stop or continue ahead at the beginning of the yellow signal. Since the yellow signal lasts only 3 s, an improper decision will result in major accidents before it turns red. Back-end crashes and crossing of intersections result from sudden stops,...
Article
Identification of bird species from their sounds has become an important area in biodiversity-related research due to the relative ease of capturing bird sounds in the commonly challenging habitat. Audio features have a massive impact on the classification task since they are the fundamental elements used to differentiate classes. As such, the extr...

The water medium is not particularly conducive for the acquisition of underwater images. This is due to its nature; with the presence of small floating particles in the water medium, causing the scattering of light and attenuation of wavelength, as well as the loss of light, especially in deep water environment. These issues make the captured under...

Bird classification using audio data can be beneficial in assisting ornithologists, bird watchers and environmentalists. However, due to the complex environment in the jungles, it is difficult to identify birds by visual inspection. Hence, identification via acoustical means may be a better option in such an environment. This study aims to classify...

Road accidents occur at traffic signals, even though traffic patrolling and awareness are increased. Accidents occurred at traffic signal junctions are a significant proportion in the overall reported road accidents. Usually, when the drivers approaching the traffic signals, at the onset of yellow, the drivers would enter into a dilemma zone, where...
Article
An intelligent support system is needed to assist in the identification of abnormalities of a human heart. The integration of signal processing with machine learning techniques is a new research trend in the studies of heart sound analysis. This paper proposes a heart sound feature dimension reduction and classification methods using supervised mac...
Article
When the drivers approaching signalized intersections (onset of yellow signal), the drivers would enter into a zone, where they will be in uncertain mode assessing their capabilities to stop or cross the intersection. Therefore, any improper decision might lead to a right-angle or back-end crash. To avoid a right-angle collision, drivers apply the...
Chapter
Full-text available
In this chapter, the introduction of the new OS kernel internals for the new metrics for the Distributed Computing Environment (DCE) and cloud performance prediction is explained. This new introduction is named as the Division of Load (DOL). The DOL method breaks down the CPU load by individual users and then separates the Disk IO load from the CPU...
Article
Full-text available
Underwater images often undergo distortions from scattering, absorption, colour loss, diffraction, polarisation, and varying attenuation depending on the light frequency, due to the water medium. This study answers problems associated with the recovery of underwater images, by developing novel depth map estimation which may be used as an intermedia...
Article

The objective of this paper is to study, analyse and investigate the main contributor of plastic pollution which has become the world major infamous problem nowadays, and to explain our platform design which aim to help in reducing the issue of floating trash. Annually, more than 2 million tonnes of plastics have been tossed to water body and event...
Conference Paper
Full-text available
This paper presents an automatic method of segmenting normal and abnormal Phonocardiography (PCG) signals by analyzing prominent peak distances, amplitudes, area, and cardiac cycle durations. Principal Component Analysis (PCA) is used to reduce the dimensions of the calculated prominent peak ratios. Subsequently, Artificial Neural Networks (ANNs) a...
Conference Paper
Full-text available
In this paper we discuss about a preliminary study which is one of the series of studies conducted to design a computer software system which helps self-educate the spoken English learners. This software system detects English language syllable stress and uses the results to guide the prospective learners towards a successful learning of spoken Eng...
Article
Facial expressions are complex, progress over time, and are challenging to interpret. The research subject of automated emotion recognition associated with the facial expressions has been a mainstream topic in computer vision focused on image processing and pattern recognition. Numerous databases of facial expressions are available to the research...
