Revision as of 18:10, 29 November 2015
A slecture by ECE student Yitong Wang (or anonymous if desired)
Partly based on the ECE438 Fall 2015 lecture material of Boutin.
Contents
1. Introduction (Implementation of Quantization)
Quantization is an operation to compress a signal by reducing a range of values to a single value. This slecture will describe the implementation of image quantization $ f(x)= \frac{1}{5} \sin x \int_{-\infty}^\alpha \pi^y dy $
2. Background
- The brightness of a photo at each pixel is typically distributed among integers from 0 to 255. However, since some images are desired to take only several values, the brightness value has to be rounded off to fit the size of the image.
- Since the quantization will obviously cause loss of data, we should try the quantization in different levels and the analyse the error.
3. Theory

4. Conclusion (Replace by appropriate section title)
Text of fourth section goes here.
5. References
