Article
Variations in perspective, illumination, occlusion, motion blur, and weatherworn degeneration of signs could all be crucial in identifying road signs. The goal of this work is to evaluate the technique's performance for image processing in detecting and recognizing triangle sign, as well as determine the optimum threshold value range for doing so....
Conference Paper
The evaluation metric for images taken in different environments such as the effect of different levels of water depth is a critical need in inland and coastal water environments. The difficulties are due to the poor lighting conditions in addition to the absorption/scattering effects which degraders image’s optical properties in final. Image range...
Chapter
Due to light refraction effect, the need to design a proper technique for underwater scene is a critical task. The problem began to be appeared at deeper levels of water and hence, one cannot distinguish nor observe the properties for underwater objects. The properties may include dimensions, color, texture, etc. So, the current paper involves such...
Conference Paper
In spite of its transparency, the determination process for the properties of submersible object into water is a difficult task. One of these difficulties arises from the differences in refractive indices between two different mediums such as air and water which changes the visual appearance of the immersed object. Such difficulties will provide un...

Article
Due to brain’s internal wiring, a beating effect will be created in it as soon as two sine waves with slightly different frequencies be applied to each ear. Brain’s response to such beat remains controversial; therefore and in addition to author’s desire toward investigate the role of beat and carrier frequencies upon the brain, this research intro...
Conference Paper
Due to its numerical procedure, an expected error occurred in applying the numerical algorithms. A challenging attempt toward using such approximation methods on digital image has been utilized here. Bisection, Newton Raphson, and secant methods are some numerical techniques which have been used here for certain considerations to test their evaluat...

An attempt to quantify the spectral response of the polychromatic light sources and drinking water samples has been presented in this research. This had been executed by an objective methods of image quality assessment, in which the criteria of error visibility (differences) between images had been applied theoretically and practically. The theoret...

Texture is one of the crucial primitives in human vision. Its analysis describes the spatial variation of an image pattern based on some mathematical procedures and models to extract an information from it. Texture features can be used after that to identify the contents of an image. So, an attempt to extract iris texture features based on Gray Lev...

Texture analysis has been considered as a popular research area in the field of image processing. Its importance comes from human visual system's dependency upon statistic features for texture discrimination purposes. Due to its huge discriminatory properties, this work has been examined iris information to see which statistical measure can be best...

Article
Without human involvement, the need for an automatic algorithms for quality assessment takes place especially for the case of distinguishing the quality of drinking water when the latter has the same color. Image quality assessment is closely related to image similarity assessment in which quality is based on the differences between a degraded imag...

The weakness of Human Auditory System (HAS) led the audio steganography process to be used in hiding data in the digital sound. Audio steganography is implemented here by using Least Significant Bit (LSB) algorithm to hide message into multiple audio files. This is achieved by 1st, 2nd, 3rd, and 4th bits hiding ratios. In a comparison to other used...

Defocus blur is considered as an important visual cue for image quality assessment which the latter plays an effective role in various image processing applications. Image quality assessment related to image similarity in which quality is based on the difference between the degraded image and the original one. Among the well-known algorithms for me...

Text data present in images contain useful information for automatic explanation, indexing, and structuring for images. Extracting information involves detection, localization, tracking, extraction, enhancement, and recognition of the text from a given image. However variations of text due to differences in color as an example make the problem of a...

The appearance of a scene depends on a variety of factors such as viewing geometry, scene structure refl ectance, illumination (sun, moon, stars, lamps), and atmospheric condition (clear air, fog, rain). As time elapses, these factors change, altering the appearance of the scene. In this research , we focus on illumination variation using sunlight...
