摘要
A method of video encoding is provided that includes computing spatial variance for video data in a block of a video sequence, estimating a first bit-rate based on the spatial variance, a transform coefficient threshold, and variance multiplicative factors empirically determined for first transform coefficients, and encoding the block based on the first bit-rate.
