In this paper, we propose a method to represent the image based on the image color constitute region, to retain the color texture information, and to reconstruct image by interpolation. The image would be segmented by the watershed algorithm to get color gradient direction as the texture information, and be represented by asymmetric and anti-packing model. The gradient direction would indicate ...

For decades, color-critical video monitoring for broadcast and post-production applications was performed on a reference (grade 1) CRT monitor, or a reference projector for cinema applications. Flat panel displays, although having clear advantages in terms of depth, longevity and insensitivity to magnetic fields, have until recently failed to produce accurate and stable pictures as required for...

Color space transformation is the process of converting color from one space to the other type of color space, which plays a very important role in image acquisition, display and color information transfer. Though CMYK space is applied to express color when using printer or phototypesetter, editing correction in CMYK color space may cause color loss and lower the speed of computer operation. Th...

In this paper, we propose a new region extraction method using chroma key with a two-tone checker pattern background. The method solves the problem in conventional chroma key techniques that foreground objects become transparent if they have the same color with the background. The method utilizes the adjacency condition between two-tone regions of the background and the geometrical information ...

Scordatura, a method of changing the tone color by tuning interval, is sometimes used for playing string instruments. Resonance one important factors in stringed In this study, frequency response was demonstrated to depend on difference between temperaments such as Pythagorean and equal temperament. addition, decay time found increase or decrease with changes conditions. It also observed that i...

The goal of the present work is to reduce the number of the training samples used in our color prediction model based on CIEXYZ using an Effective Coverage Map while keeping satisfying prediction. A general approach is proposed in this paper to choose the best reference combination for the training samples. The approach is based on the dot gain behavior of each primary ink, which is characteriz...

There is a well-known shortage of racial diversity in medical textbooks and literature contributing to race-based health care inequalities1. We present the case black puertorrican 58-year-old female who developed painful non-pruritic blistering ulcer inner oral mucosa with associated erythema six months prior evaluation. She was misdiagnosed on multiple occasions leading rapid progression disea...
