An Image Resolution: A Survey

Resolution can be calculated by counting the pixels that are present in an image. It can also be calculated by counting the image width and height. Our system's screen is also set at a particular resolution. In order to adjust the screen the option of zoom in and zoom out are used. As large as the screen is available, then the larger resolution is being set. File size can be reduced when you select the image as JPG file, and select the amount of compression before saving. In this paper we will look on the different resolution techniques and also its types. Survey has been done from different research papers.
