Whether you are taking photos with your iPhone, watching a DVD, reading a pdf, or checking out Google images, digital images are everywhere. This is quite amazing because these images require a lot of memory. The memory required by these complex images makes them hard to store and time-consuming to download.Almost everyone is familiar with pixels – the rows of tiny dots that make up an image. The resolution of an image depends upon the number of pixels used in a particular image. A raster image is a data structure that stores information about those pixels. The data about these pixels is compressed, using a particular encoding algorithm so that the image takes up less memory. A lossless algorithm permits the image to be reproduced without losing any information. A lossy algorithm is one in which some of the data is lost so that the image can be compressed even more.Which method of digital image compression results in the best-quality photos?
