Study of Grayscale Image in Image Processing

Image is made by number of pixels and different major parameters like color and monochrome (sometimes also known as black & white image or property). Image is processed and executed by an image processing techniques. So image processing is the major part of signal processing. Gray scale conversion is also a vital part of image processing. RGB or color information has a 3 dimensional property which makes signal processing so much bulky and heavy to remove this drawbacks gray scale conversion is necessary. So in this paper we will discuss about advantages of gray scale images and how they are used in image processing
