For digital color devices, complex relationship exists between their input image pixel values and the output color chromatic values, gamut mapping between them as well. The linear models are difficult to describe this relationship effectively. In the study, based on BP neural network, a gamut mapping model with micro space sections is proposed. The gamut mapping model maps color from monitor ga...

This paper presents an attempt at ‘non-verbal mapping’ between music and images. We use physical parameters of key, height and timbre as sound, and hue, brightness and chroma as color, to clarify their direct correspondence. First we derive a mapping rule between sound and color from those with such special abilities as ‘colored hearing’. Next we apply the mapping to everyday people using a pai...

Tone mapping algorithms offer sophisticated methods for mapping a real-world luminance range to the luminance range of the output medium but they often cause changes in color appearance. In this work we conduct a series of subjective appearance matching experiments to measure the change in image colorfulness after contrast compression and enhancement. The results indicate that the relation betw...

The interrelationships among spatial distribution in the red, green, and blue channels of texture images of differently woven textile fabrics are investigated. A computational model for color mapping is developed based on the channel proportionality found in the investigation. The computational model developed has two modes: gray-to-color mapping (GCM) and color-to-color mapping (CCM) that deal...

We present new imaging of the surface of Pluto and Charon obtained during 2002–2003 with the Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) instrument. Using these data, we construct two-color albedo maps for the surfaces of both Pluto and Charon. Similar mapping techniques are used to re-process HST/Faint Object Camera (FOC) images taken in 1994. The FOC data provide informatio...

Recent color transfer methods use local information to learn the transformation from a source to an exemplar image, and then transfer this appearance change to a target image. These solutions achieve very successful results for general mood changes, e.g., changing the appearance of an image from “sunny” to “overcast”. However, such methods have a hard time creating new image content, such as le...

Objective: This prospective study was undertaken to assess the sensitivity and specificity of color flow mapping and pulse Doppler waveform in identifying malignancy preoperatively in adnexal masses in perimenopausal women. Materials and methods: A total of 100 cases with adnexal masses in perimenopausal women were scanned, underwent color flow mapping and pulsed Doppler waveform studies. These...
