Summary
Encoding the message "WIKI" with arithmetic coding
| 1. | The letter frequencies are found. |
|---|---|
| 2. | The interval [0, 1) is partitioned in the ratio of the frequencies. |
| 3–5. | The corresponding interval is iteratively partitioned for each letter in the message. |
| 6. | Any value in the final interval is chosen to represent the message. |
| 2*–6*. | The partitioning and value if the message were "KIWI" instead. |
| Description |
English: Visualisation of the use of arithmetic coding to encode the message "WIKI" by CMG Lee. Step 1: The frequencies of the letters are found. Step 2: The interval [0, 1) is partitioned in the ratio of the frequencies. Steps 3 to 5: the corresponding interval is iteratively partitioned for each letters in the message. Step 6: Any value in the final interval is chosen to represent the message. Steps 2* to 6*: The partitioning and value if the message were "KIWI" instead. |
