Abstract
Estimation of the code size of variable length encoding of quantized DCT coefficients by summation over histogram bins of products of number of bin members and a code size of an average run of zero coefficients coupled with a representative level from the bin. The estimation provides low-complexity feedback for quantization level adjustment to obtain variable length code size target without actual performance of a quantization level plus variable length encoding.
