Claim 7:
8. A method comprising:
receiving, by a coding control component of an encoder, a digital video frame; and
dividing, by the coding control component of the encoder, the digital video frame onto a plurality of coding units (CUs);
performing, by a transform component of the encoder, block transforms on the plurality of CUs, to generate a plurality of transform coefficients;
determining, by a quantize component of the encoder, a plurality of parameters of a structural similarity index (SSIM)-based distortion model for the plurality of CUs, and
quantizing, by the quantize component of the encoder, the plurality of transform coefficients based on the plurality of parameters, to generate a plurality of quantized transform coefficients.
