Question
A 640 times 480 black and white image is stored using 8 bits per pixel without compression. What is its size in kB? Answer: _____ How many pixels would the above image have? Answer: _____ If we convolve the above image with the filter [1/25 1/25 1/25 1/25 1/25 1/25 1/25 1/25 1/25 1/25 1/25 1/25 1/25 1/25 1/25 1/25 1/25 1/25 1/25 1/25 1/25 1/25 1/25 1/25 1/25] then how many pixels would the resulting image have? Answer: _____ Instead, if we use the filter shown below: [1/25 1/25 1/25 1/25 1/25 -1/25 -1/25 -1/25 -1/25 -1/25 1/25 1/25 1/25 1/25 1/25 -1/25 -1/25 -1/25 -1/25 -1/25 1/25 1/25 1/25 1/25 1/25] how many pixels would the resulting image have? Answer: _____Explanation / Answer

Pixels are usually stored in bytes and its range is from 0 to 255.
The required size of 640*480 back and white image is 307.2kB
