Background Endometrial receptivity is one of parameters which determine the reproductive outcome in in vitro fertilization programs. A good blood supply towards the endometrium is usually considered to be an essential requirement for implantation. Blood vessels of the endometrium can be detected by transvaginal color and pulse Doppler sonography. Color Doppler assessment permits better visualiz...

This paper proposes a method for designing a color lookup table (CLUT) that can simultaneously process gamut mapping and color space conversion without any complex computation. After constructing a LUT composed of the scanner and printer gamuts, fictive sample points are uniformly selected in CIELAB space and CMY values computed using gamut mapping. The scanner input RGB image is then converted...

We present an interactive image enhancement technique to adjust the global color composition of an image by finding and replacing color gradients. We show how color gradient transformations can perform the basic operations of color editing. To recolor an image, the user designates a mapping of source color gradients to corresponding target color gradients. Each color gradient can be represented...

In this work, a novel and generic method for example-based color transfer is presented. The color transfer is formulated in two steps: first, an example-based Chromatic Adaptation Transform (CAT) has been designed to obtain an illuminant matching between input and example images. Second, the dominant colors of the input and example images are optimally mapped. The main strength of the method co...

Mappings between color spaces are ubiquitous in image processing problems such as gamut mapping, decolorization, and image optimization for color-blind people. Simple color transformations often result in information loss and ambiguities (for example, when mapping from RGB to grayscale), and one wishes to find an image-specific transformation that would preserve as much as possible the structur...

Color gamut mapping plays a crucial role in color management. Depending on the application, it is sometimes desirable to perform color gamut mapping by shifting the lightness and compressing the chroma of an out-of-gamut color while preserving the perceived hue of the color. The term Òperceived hueÓ is used to distinguish between the visual sensation of hue and metric hue angle (e.g., CIELAB hu...

T h e computation of immediate texture discrimination involves f i nd ing boundaries between regions of dif fer ing texture. Th i s paper describes two operators which together appear necessary and probably sufficient to accomplish this. Texture can be regarded as the structural property of surfaces with respect to their constituents. The formation of texture crucially depends on small, fairly ...

We propose an exploratory data analysis approach when data are observed as intervals in a nonparametric regression setting. The interval-valued data contain richer information than single-valued data in the sense that they provide both center and range information of the underlying structure. Conventionally, these two attributes have been studied separately as traditional tools can be readily u...

This paper describes a prototype system for quickly developing joint military courses of action. The system, SOCAP (System for Operations Crisis Action Planning), combines a newly extended version of an AI planning system, SIPE{2 (System for Interactive Planning and Execution), with a color map display and applies this technology to military operations planning. This paper describes the Socap p...
