Document Summary
Assignment #2: pixel: a iny dot on the screen represening a part of an image (looks like a litle square when zoomed in). It is a form of measurement that makes up an image. It is a sample point and contains color informaion. Aliasing: the jagged (zig-zag) appearance of curved or diagonal lines on a low resoluion monitor. The rough edges that are shown from poor resoluion especially in pixel based images, due to under-sampling. Ani-aliasing: a technique used to add greater realism or clarity to a digital image by smoothing jagged edges on curved lines and diagonals. Smoothing out the rough edges of the pixels of the images to create a clearer/more professional quality: binary image: 1 bit per pixel uses 2 colors-black and white bit depth is 1. 256 gray levels in varying brightness (black white) bit depth is 8.
