Document Summary

1. what is sampling and quantizing mean wrt images: sampling: images taken from scanner, digital camera graphics application, represented by a grid (array, matrix) of squares called pixels (picture elements, pixel is smallest image component and thus shows the smallest detail, arranged in column and rows, how many parts (pixels) will i break the image up into, quantizing for images: measurement for each bit is based on binary system (base 2, 1 bit is either 0 or 1 , (1 bit) 21 = 2 values (0, 1) black, white, (2 bit) 22 = 4 values (00,01,11,10) black, light gray, dark gray, white, (x bit) 2x= y values = max # of combinations (values, important: 2x = #of combinations = maximum number of colors available to assign to a pixel to represent image, 1 bit= 2 colors represent color of each pixel, 8 bits= max of 256 colors, 24 bits= max of 16 million colors)
