DQ-Zip
- Highly-Efficient Lossless Compression for Many Types of Data -

TECHNITEIA’s DQ-Zip offers the ultimate resource in compression software, able to improve the performances of the algorithm used in WinZip, ZipMagic, and PkZip by an average of 15%.

• The products of DQZip line incorporate our DQ-Zip software with a set of file specific compression filters, which dramatically speed up file transfer times. This copes with the necessity for Internet/Intranet market of saving communication costs. The use of TECHNITEIA Filters is an example of data specific compression.
• Compression is greatly increased when more accurate predictions on the data at hand are available. By using filters for specific file formats, we obtain greater accuracy in these predictions, so to achieve greater compression performance. In some cases where compression filters are essential, the compression performance can increase also by a factor of 200 to 400% and more, when compared to Zip algorithms, without filters! See below for further information.
• In this way, we can offer personalized solutions to our customers, for satisfying their specific compression needs.

What Is A Universal Coder

• Universal coders apply the same algorithm to all files regardless of the data type. The best known universal coder is an implementation of the Lempel-Ziv algorithm that Phil Katz put out as the PKzip shareware product many years ago. This coder is still used in almost all commercial lossless compressors (WinZip, ZipMagic, Zippy...), which merely attach their user interface to the PKzip coder.

DQ-Zip Universal Coder

• The TECHNITEIA DQ-Zip Universal Coder uses a new and proprietary compression
  algorithm. The algorithm was developed by A.L. Perrone. On most data files, it achieves significantly better compression rates than Zip, and encodes fast enough to be used in real-time communications products. The DQ-Zip Universal Coder is available as a Windows DLL and the code can be easily ported to other operating systems, for embedded use within archive and communications products.
• The algorithm is also ideally suited for implementation in hardware data compression (both DSP and ASIC).

Performances

• Performances vary according to the type of data and the size of the data blocks to be encoded. In our performance tests on a large number of files of various types, the DQ-Zip Universal Coder achieved an overall compression gain of 20% over Zip.
  

Options

• TECHNITEIA has developed customized Filters, which increase the compression performance on specific file formats.
• The DQ-Zip can use customized Filters supporting specific file formats. The basic system includes Filters for the most commonly used web formats.
• Our Graphics Filters allow the DQZipImage compression system to be used on many common image formats. We currently have Filters for Targa, Bmp, TIF, Ppm etc. in addition to the Jpeg & Gif Filters that . Filters for other formats can be prepared upon request.
• Our Database Filter typically achieves twice the compression performance of Zip algorithms, so that large databases can be transmitted in half the time.
• Our Office Filters increase compression of the files generated by the world's most used office programs. We currently have Filters, which support Microsoft Excel, Microsoft Word, Microsoft Access and Microsoft Powerpoint.
  

DQSqueezeDoc
- Highly-Efficient Lossy Compression for Text and Images -

• DQSqueezeDoc enables high compression rates and high image quality for original or scanned documents containing images and text.

• DQSqueezeDoc combines the high compression rates of black and white compression techniques with the high image quality of 24 bit true color.

• DQSqueezeDoc performs an Image analysis, separating the original document into text and image regions. Text regions are compressed using our state-of-the-art bi tonal compression algorithm while the image regions are compressed using a modified wavelet algorithm including our Dynamic Quantization.

Advantages

• The “bi tonal” compression rate is 20%-40% better than the industry standard Fax Group 4 algorithm.

• Image compression with high quality at rates 1:100 and higher.

• Lossless compression/decompression of the text components, preserving the text color.

• Applicable for documents including images, graphics and symbols

• Sharp border between images and text through automatic document separation

• Total compression with high quality at rates 1:50 and higher

Application Areas

DQSqueezeDoc is applicable wherever digital documents are processed, stored, transmitted  accessed or archived:

• text documents
• newspapers and magazines
• catalogs
• forms etc.

Examples

• Hospital: x-ray images integrated with patient documentation

• Real Estate: Internet advertising (large documentation with photos)

• Insurance Company: Internet advertising (large documentation with photos)

Supported Platforms and Versions

• DQSqueezeDoc is available for a variety of platforms including Windows, Macintosh,
  Linux, and Sun Solaris.
