Dark. Water Image Compression Presentation

Dark. Water: Image Compression Capabilities • Capable of compressing large and small images. • Reduces 190 MB size image by 82 (8, 200%) times whilst remaining visually loss-less • Can be enlarged by up to 1500 times on the compressed file to show clear details

Dark. Water Compression Software • Reduces a 190 Megabyte image by up to 10, 000 times whilst it still remains visually acceptable (see next slide). • Reduces vastly the amount of storage required. Up to 10 times less storage required using JPEG to enhanced JPEG compression. Up to 100 times less storage required for larger images. Up to 100 times less storage COST. No LOSS of quality. • Reduces Transmission Time – to maximise available bandwidth, even if it is a scarce resource.

Centrex Dark. Water Compression Technology • Dark. Water compression allows the images to be saved and then compressed allowing important information to be taken from large images and stored in small file sizes. • In this example (next slide), the large (150 Mb+) Satellite photo of San Diego and the Darkwater compressed image (19. 58 kb) is shown being transmitted in Full size and Darkwater compressed size across all types of IT transmission • Dark. Water compression would remove transmission time over a 9. 6 K modem to 16 seconds (from several hours) and to 1. 6 seconds on a 56 K modem, from over an hour.

JPEG Compression demonstration Dark. Water Compression Technology • Dark. Water compression technology also greatly reduces the file size of already small and compressed JPEG images. • Dark. Water compression can reduce a JPEG image by up to 150 times with visually acceptable quality, and by ten times with visually lossless quality.

Dark. Water Compression Technology • Dark. Water compression due to it’s high compression rates and yet visually lossless results can be used to reduce medical images in size. • Dark. Water can reduce medical images by up to 2, 700 times (270, 000%) whilst still leaving them visually acceptable, or by up to 1, 000 times (100, 000%) leaving them visually lossless. • Heavily reduces the storage space and the bandwidth required to quickly send these often life saving medical images.
