One way to increment a Gray code number is to convert it into ordinary binary code, add one to it with a standard binary adder, and then convert the result back to Gray code. Other methods of counting in Gray code are discussed in a report by Robert W. Doran , including taking the output from the first latches of the master-slave flip flops in ...
Thresholding (image processing) Original image. The binary image resulting from a thresholding of the original image. In digital image processing, thresholding is the simplest method of segmenting images. From a grayscale image, thresholding can be used to create binary images. [1]
Grayscale images are distinct from one-bit bi-tonal black-and-white images, which, in the context of computer imaging, are images with only two colors: black and white (also called bilevel or binary images). Grayscale images have many shades of gray in between.
Shades of gray were rendered by intermittently raising and lowering the pen, depending upon the luminance of the gray desired. Ranger's invention used capacitors to store charges, and vacuum tube comparators to determine when the present luminance, plus any accumulated error, was above a threshold (causing the pen to be raised) or below ...
Netpbm (formerly Pbmplus) is an open-source package of graphics programs and a programming library. It is used mainly in the Unix world, where one can find it included in all major open-source operating system distributions, but also works on Microsoft Windows, macOS, and other operating systems.
Gamma correction is a type of power law function whose exponent is the Greek letter gamma ( γ ). It should not be confused with the mathematical Gamma function. The lower case gamma, γ, is a parameter of the former; the upper case letter, Γ, is the name of (and symbol used for) the latter (as in Γ ( x )).
In the programming language C, a conversion from a Gray code g to an unsigned binary representation b can be achieved efficiently through: b = g; while (g >>= 1) {b ^= g;} INTERNATIONAL STANDARD ISO/IEC 9899, Programming languages — C 6.5.7 Bitwise shift operators
Dither is routinely used in processing of both digital audio and video data, and is often one of the last stages of mastering audio to a CD . A common use of dither is converting a grayscale image to black and white, so that the density of black dots in the new image approximates the average gray level in the original.
