Embodiments of a coding system and method are disclosed. One method embodiment includes determining a Cauchy-based probability density function fit to a statistical distribution of coefficients generated from a transformed image frame block that are to be quantized, and estimating rate and distortion of quantized coefficients based on the Cauchy-based probability density function.
