Adaptive Spline-Wavelet Image Encoding and Real-Time Synthesis
A wavelet-based image-encoding is described which, when used in conjunction with the Di erence Engine (a customdesigned VLSI display processor) allows us to reconstruct an image in real-time without the need to set each pixel explicitly. The image is compressed using a quadratic splinewavelet transform; when reconstructing, an image-adaptive instruction generator attempts to produce the minimal instruction stream to give a good reproduction. The wavelet coe cients are used to decide which regions of the detail images should be retained in the multi-resolution analysis (MRA). A decision is made for each scan-line as to whether it is more economical, in terms of rendering time, to use the `truncated MRA' or to set the pixels directly. The above approach provides a signi cant gain over standard image reconstruction/rendering schemes.
