چکیده

Color images have a gamut that typically spans three dimensions. Nevertheless, several important applications, such as the creation of grayscale images for printing and the re-coloring of images for color-deficient viewers, require a reduction of gamut dimension. This paper describes a technique for preserving visual detail while reducing gamut dimension. The technique is derived by focusing on the problem of converting color images to grayscale. A straightforward extension is then provided that allows re-coloring images for color-deficient viewers. Care is taken so that the resulting images remain within the available gamut and visual artifacts are not introduced.

A Spectral Gamut-Mapping Environment with Rendering Parameter Feedback

This paper proposes a prototypical environment for gamut mapping in spectral space. Images are rendered in terms of light and material parameters by a symbolic ray tracer, and the parameter ranges are adjusted, without re-rendering, to bring the image into the output device’s spectral gamut. There is a growing disparity between the high dynamic range images produced by spectral renderers and th...

False positive lower limb lymphoscintigraphy due to inadvertent intra-vascular injection of the tracer: Importance of tracer re-injection

We presented a 30 year-old woman presented with symmetrical swelling of the lower limbs since 5 years ago with sparing of the feet. She was highly suspicious of having lipoedema and was referred for lower limb lymphoscintigraphy to rule out possible lymphedema. Lymphoscintigraphy images showed asymmetrical injection sites and unusually high liver and spleen uptake. Inguinal nodes was not visual...

Palette-Based Image Segmentation using HSL Space

This paper describes a palette-based colored image segmentation system. In this paper we analyzed the properties of Hue, Saturation, and Luminance (HSL) color space with emphasis on the visual perception of the variation in Hue, Saturation and Luminance values of palette colors. The proposed algorithm based on the concept of re-coloring the palette colors of 256-color images using the propertie...

The gamuts of input and output colour imaging media

The colour gamuts of colour imaging media are important parameters in the reproduction of colour images between them and their assumed magnitudes directly influence the degree to which colours are modified. In spite of this, the determination of gamut boundaries is often done in a way that ignores some basic implications that follow from the definition of colour gamuts. This is partly due to th...

Acyclic and k-distance coloring of the grid

In this paper, we give a relatively simple though very efficient way to color the d-dimensional grid G(n1, n2, . . . , nd) (with ni vertices in each dimension 1 i d), for two different types of vertex colorings: (1) acyclic coloring of graphs, in which we color the vertices such that (i) no two neighbors are assigned the same color and (ii) for any two colors i and j , the subgraph induced by t...
