- Supposing SIGMA = { 0, 1}
- If the probability P(0) is very high and P(1) is close to ZERO arithmetic
- coding doesn't seem to work !!
- I mean supposing the string is pure ZEROES then arithmetic coding interval
- will decrease very slowly. This would result in a very long encoding. On
- the other hand the entropy of this data is very low!!
- Any help ??
-
- Thanks.
