Abstract
Systems and methods for intelligent quantization for video compression are provided. In some embodiments, the methods and systems estimate a rate-distortion function is for video coding. An offset to a reconstruction process is applied, where the offset is determined based upon a frequency dependent variable and a quantization step size. The offset is then derived by transmitting the frequency dependent variable to a decoder. Additionally, a transform coefficient may be estimated as either a Laplacian or Cauchy distributions with a mean of zero and α as a frequency dependent parameter. The offset at an encoder may be modified based on the frequency dependent variable. Modifying the offset minimizes overall distortion by moving the quantization step size closer to a centroid of the Laplacian or Cauchy distribution. Additionally, a quantization bin size may be altered to optimize distortion, and the system may determine which frequency coefficients to utilize.
