Image coding with an Linfinity norm and confidence interval criteria
1Department of Research in Speech Communication, CNET, Lannion, France.
Summary
This study introduces a novel image coding method using an Linfinity-norm criterion. It enables flexible lossless or controlled lossy compression by managing reconstruction error within a confidence interval.
Area of Science:
- Digital image processing
- Information theory
- Computer vision
Background:
- Traditional image coding methods often face limitations in balancing compression efficiency and reconstruction fidelity.
- Existing techniques may not offer sufficient flexibility for both lossless and controlled lossy compression scenarios.
Purpose of the Study:
- To investigate a new image coding technique.
- To leverage the Linfinity-norm criterion and statistical properties of reconstruction error.
- To achieve flexible lossless and controlled lossy image compression.
Main Methods:
- Image preprocessing using linear prediction and iterated filterbanks.
- Quantization and encoding of image data.
- Reconstruction of images within a specified confidence interval.
- Exploitation of statistical properties of the reconstruction error.
Main Results:
- The proposed technique allows for both lossless and controlled lossy image coding.
- Reconstruction error is managed within a defined confidence interval.
- The method is compatible with existing image coding techniques.
- Controlled lossy compression can be achieved with a specified percentage of differing pixels.
Conclusions:
- The developed image coding technique offers significant flexibility.
- It effectively balances compression and fidelity through the Linfinity-norm criterion.
- The approach is adaptable and integrates with prior methods for enhanced performance.

Interpretation of Confidence Intervals
A confidence interval is a better estimate of the population than a point estimate, as it uses a range of values from a sample instead of a single value.
Confidence intervals have confidence coefficients that are crucial for their interpretation. The most common confidence coefficients are 0.90, 0.95, and 0.99, which can be written as percentages–90%, 95%, and 99%, respectively.
Suppose a person calculates a confidence interval with a confidence coefficient of 0.95. In that case, they can...

Confidence Intervals
An unbiased point estimate is often insufficient to predict a population estimate, such as population mean or population proportion. In this scenario, a confidence interval is used. A confidence interval is an estimate similar to a sample proportion. However, unlike the point estimate which is a single value, the confidence interval contains a range of values. These values have lower and upper limits, known as confidence limits, and can be designated as L1 and L2, respectively.

Confidence Coefficient
The confidence coefficient is also known as the confidence level or degree of confidence. It is the percent expression for the probability, 1-α, that the confidence interval contains the true population parameter assuming that the confidence interval is obtained after sufficient unbiased sampling; for example, if the CL = 90%, then in 90 out of 100 samples the interval estimate will enclose the true population parameter. Here α is the area under the curve, distributed equally under both the...
Uncertainty: Confidence Intervals
The confidence interval is the range of values around the mean that contains the true mean. It is expressed as a probability percentage. The interpretation of a 95% confidence interval, for instance, is that the statistician is 95% confident that the true mean falls within the interval. The upper and lower limits of this range are known as confidence limits. The confidence limits for the true mean are estimated from the sample's mean, the standard deviation, and the statistical factor 't,' or...
Critical Values
A critical value is a definite value obtained from a particular probability distribution at a predecided confidence level (or a predecided significance level) for a given population parameter. The critical value provides demarcation that separates the sample statistics that are likely to occur from the ones that are unlikely to occur based on the given probability distribution and the population parameter to be estimated. The critical value for normal distribution is obtained from the z...
Estimating Population Mean with Unknown Standard Deviation
In practice, we rarely know the population standard deviation. In the past, when the sample size was large, this did not present a problem to statisticians. They used the sample standard deviation s as an estimate for σ and proceeded as before to calculate a confidence interval with close enough results. However, statisticians ran into problems when the sample size was small. A small sample size caused inaccuracies in the confidence interval.
