In the JPEG2000 standard the very cost intensive EBCOT encoder based on an arithmetic encoder with an embedded quantization is said to be the optimum. Embedded systems with limited processing power have difficulties to encode images into this JPEG2000 image format due to its high processing load. A rekursive optimization of the quantization is not possible. This paper proposes a new method based on a model for subband quantization behavior of two-dimensional wavelet transformations to estimate a good quantizer stepsize for data rate limitations. With an additional, simple optimization algorithm an average variation in the resulting data length of
