Marvin Hugley Jr Problem 1 (200 points). Determine the file size in kilobytes of a 400 X 600 image with a color depth of 24 bits. What is the size of the same file as a black and white image? 400x600x24/8/1024=703.1 400x600x1/24/1024=9.76 Determine the file size in megabytes of a 3-minute audio file that was sampled at 32 KHz, having a bit depth of 8 bits and was recorded in stereo. 3x60x32000x8/1024/1024=43.94 Determine the file size in gigabytes of a video clip in 4K (specifically, the UW4K standard), color depth of 24 bits, frame rate of 60 fps (frames per second), and a 2 hour duration. In all of the above, assume no compression was used. 3840x2160x60x120/24/1024/1024/1024=2.31 Problem 2 (100 points). Explain through the use of a detailed pictorial example the way spatial compression takes advantage of similarities in color to further compress an image. Spatial take advantage of color by only storing the color and number once. So if you have 10 reds instead of you storing red 10 times you only have to store the 10 once and the red once instead of storing it 10 times. Problem 3 (100 points). Given four video clips in PAL, NTSC, Theater, and 4K formats and a timebase of 60 fps, devise frame rate conversions to unify the frame rates of all movies into the frame rate of the timebase. Provide examples of frame duplication for each movie
