LuraWave
LuraWave compression is based on wavelet algorithms (mathematical expressions that encode an image into a series of decomposed bands). Each band contains a representation of the entire image, with the various bands containing details of the image at every level, from textures to fine details. A JPEG compresses images in 8x8 blocks, resulting in blocking artifacts at high compression rates. LuraWave's wavelet technology allows for richer content and higher resolution at a fraction of the original size.
Full spectrum of compression schemes from pure lossless (pixel identical), to near lossless or lossy compression.
Progressive display of images
Precise control over compression and decompression rates.
Scalable image size and quality. The whole image may be reconstructed with only a fraction of the compressed data source (e.g., 1% of the data for a thumbnail version, 10%, 50%, etc. depending on display needs).
Encryption (password protection) option for images
Higher security against transmission interruption or disturbance: lower probability of transmission disturbances due to reduced transmission times.
Valuable money savings: less disk space required and reduced transmission costs.
User selectable compression ratio included: provides flexible control over image quality. Select compression ratios up to 200:1.
Precise reconstruction of edges: none of the blocking effects common with JPEGs.
