Perceptual and Motor Skills, 1977
There is renewed interest by psychologists in mental imagery. While practical uses of imagery are being rapidly developed, there still remains a great deal to learn about imaging itself. One aspect of imaging is color. A review of the literature provided no research data as to which colors were easiest or hardest to image.

Semantic colorization with internet images
ACM Transactions on Graphics, 2011Colorization of a grayscale photograph often requires considerable effort from the user, either by placing numerous color scribbles over the image to initialize a color propagation algorithm, or by looking for a suitable reference image from which color information can be transferred.

Color and Scale: The Spatial Structure of Color Images
2000For grey-value images, it is well accepted that the neighborhood rather than the pixel carries the geometrical interpretation. Interestingly the spatial configuration of the neighborhood is the basis for the perception of humans. Common practise in color image processing, is to use the color information without considering the spatial structure. We aim

Digital color imaging with color constancy
Systems and Computers in Japan, 2002Abstract“Color constancy” which gives almost constant color perception of an object under illumination of various colors, is an important characteristic in identifying objects by our color vision. This paper proposes an algorithm to add color constancy to a digital camera, which reconstructs an image under arbitrary light conditions by using a pair of ...

In this chapter, color and color spaces are introduced; without excellent color, images and video would look unacceptable. But how is this accomplished in the real world, light bounces off surfaces and the resulting spectrum enter the eye. Retinal sensors then take over, forming a trio of signal values in (combinations of) red, green, and blue.

Color emotions for multi‐colored images
Color Research & Application, 2011AbstractWe investigate the emotional response to colors in ordinary multicolored images. In psychophysical experiments, using both category scaling and interval scaling, observers are asked to judge images using three emotion factors: activity, weight, and heat.

RadioGraphics, 1994
The most recent technology change in diagnostic ultrasound is color flow imaging (CFI), which is a merging of gray-scale and motion-detection processing to produce an image that depicts soft tissue in gray scale and blood flow in color. Currently, CFI comes in three forms: synchronous signal processing, asynchronous signal processing, and time domain ...

Compression of color images [PDF]
, 2002 In this chapter we intend to cover the basic aspects of color image compression. Basic aspects of color images can be found elsewhere in this book and compression details can also be easily found in the literature. Even though we give a very brief introduction to compression methods, we intend to explore the issues pertaining to the intersection of the

Scanner for color images with a one-color laser
Applied Optics, 1978A real-time scanning method for color images that uses a single one-color laser is described. The image is first encoded by a modified gamma-Ruticon erasable image buffer into three superimposed surface relief images that represent the red, green, and blue color separations of the original.

Color image processing is one of the newest and most exciting areas of electronic image processing. Until recently, the computing hardware required to store and manipulate color images was limited to a special few. Today, it is not uncommon to find a standard desktop computer system with a true-color 24-bit display, at least 8 million bytes of memory ...
