This study describes a detailed study of the effect of finite precision computation on wavelet-based image compression. Specifically, we examine how the quality of the final decoded image is affected by various choices that a hardware designed will have to make, such as choice of wavelet (integer or real), fixed-point attributes (number of integer and fractional bits), and compression. The algorithm studied here is that adopted by the JPEG 2000 committee, and it uses trellis-coded quantization on the wavelet coefficients, followed by bit-plane coding.
