In today’s technological era human beings are mostly interested in quality and purity of photographs or images. With the digital camera’s invention, capturing images has become extremely easy and widespread, while image data has become more robust and easy to manipulate. Among the many possible image-processing options, users have become increasingly interested in changing an image’s tone or mo...

Bi4V2O11 (BiVO) is an Aurivillius-type layered compound that exhibits a red color, and has been attracting attention for its non-toxicity. In this study, we have synthesized variety of metal oxide-doped Bi4V2O11, aimed to evaluate the effect doped element on color tone pigments. Bi2O3 V2O5 were weighed 2:1 in mole fraction mixed dry-ball mill with zirconia media 10 min. Next, transition oxides ...

We propose a complete methodology for the control of the color responses of the input/output devices for color facsimile. An initial calibration of both scanner and printer is done offline. The color response of each device is then modelized by 3D non-linear transformations linking their specific RGB/YMC color space with the standard CIELAB color space. These transformations are then quickly ca...

A testing procedure for characterizing both the color and spatial image quality of trichromatic digital cameras, which are used to photograph paintings in cultural heritage institutions, is described. This testing procedure is target-based, thus providing objective measures of quality. The majority of the testing procedure followed current standards from national and international organizations...

Synesthesia is an experience in which stimulation in one sensory or cognitive stream leads to associated experiences in a second, unstimulated stream. Although synesthesia is often referred to as a "neurological condition," it is not listed in the DSM IV or the ICD classifications, as it generally does not interfere with normal daily functioning. However, its high prevalence rate (one in 23) me...

Visible light communication (VLC) using LEDs has attracted significant attention recently for the future secure, license-free and electromagnetic-interference (EMI)-free optical wireless communication. Dimming technique in LED lamp is advantageous for energy efficiency. Color control can be performed in the red-green-blue (RGB) LEDs by using dimming technique. It is highly desirable to employ d...

Many basic, but very useful features, for characterizing an image or calculating the similarity between two images are based on color information. Psychological studies show that beyond the tone of color, different colors are also associated with different emotions. Thus, two colors that trigger the same impression are most likely considered to be more similar than two colors which trigger the ...

Shadows appear in remote sensing images due to elevated objects. Shadows cause hindrance to correct feature extraction of image features like buildings ,towers etc. in urban areas it may also cause false color tone and shape distortion of objects, which degrades the quality of images. Hence, it is important to segment shadow regions and restore their information for image interpretation. This p...
