** All grayscale algorithms use the same basic three-step process: Get the red**, green, and blue values of a pixel Use fancy math to turn those numbers into a single gray value Replace the original red, green, and blue values with the new gray valu If each color pixel is described by a triple (R, G, B) of intensities for red, green, and blue, how do you map that to a single number giving a grayscale value? The GIMP image software has three algorithms. The lightness method averages the most prominent and least prominent colors: (max (R, G, B) + min (R, G, B)) / 2

Since its an RGB image, so it means that you have add r with g with b and then divide it by 3 to get your desired grayscale image. Its done in this way The Grayscale Bitcoin Investment Trust is the first bitcoin-only publicly traded vehicle, which hit the markets in 2013. And yes, if you purchased the GBTC stock at this time - and held on. •This paper presents a new method of parameterized histogram equalization for grayscale images, which is called the gradient based histogram equalization (GB-HE). • The histogram equalization is performed on the low-pass filtered image by means of a symmetric gradient operator Earn points Gray Scale Image or a Grey Scale Image, also known as grayscale. According to the logarithmic relationship between white and black is divided into a number of grades, known as gray. Gray is divided into 256 levels One such type of Gray code is the n-ary Gray code, also known as a non-Boolean Gray code. As the name implies, this type of Gray code uses non- Boolean values in its encodings. For example, a 3-ary ( ternary) Gray code would use the values {0, 1, 2}. The ( n , k )- Gray code is the n -ary Gray code with k digits

Grayscale Conversion Algorithm. For this example, we'll write code to change the flowers.jpg image to grayscale, using the average strategy: for each pixel, compute the average of its red/green/blue values. This average number represents the brightness of the pixel 0..255. Then set the red, green, and blue values of the pixel to be that. A grayscale image captures the intensity of light in pixels. In digital image processing, intensity values are discrete integers ranging from 0 as the lowest intensity or darkest, to 255 as the highest intensity or brightest. As opposed to RGB images with numerous color variations, disparity between darkness and brightness or namely contrast is.

Face Detection: it has the objective of finding the faces (location and size) in an image and probably extract them to be used by the face recognition algorithm. Face Recognition : with the facial images already extracted, cropped, resized and usually converted to grayscale, the face recognition algorithm is responsible for finding. The reason is that we are getting more blue and red channel noise, whereas in the grayscale mode change operation the algorithm is giving us a remix of 60% of the clean, detailed green channel. Via Decompose RGB ¶ A third method is to consider the red/green/blue channels of the image. Each one can be represented as an independent grayscale image
