Lecture03-Sampling
PROBLEM TO BE SOLVED: To reduce the processing load for sampling and displaying a compressed image so as to shorten the processing time length therefor. SOLUTION: Huffman decoding (S16), run length Huffman decoding (S17), and inverse quantization (S18) are performed on a JPEG image to be...
measurement of each sample point on a numeric scale. Known as "quantizing," the sample point is turned into the closest whole number. The more granular the scale (the more increments), the more accurate the digital sample represents the original analog signal. Seeoversampling,quantizationandPCM....
The error introduced in the processing of digital signals due to quantization depends on the format of the numbers, the quantization method (truncation or rounding), the number of bits used to represent signal values and filter coefficients, and so on. Details can be found in Mitra (1998) and...
