Abstract
A statistically lossless transform (SLT) can be used with data (e.g., image data) to be compressed. Prior to compression, an SLT stabilizes the variance for a read noise+Poisson process. The SLT redistributes (image) data that has been quantized with a linear uniform quantizer and essentially assures there are no gaps in the output values (i.e., all output digital values are used). The SLT re-quantizes the data with a quantization interval width that is proportional to the standard deviation of the process.
