PixelLive (VFZ/PFZ) Overview
 |
PixelLive is an image format developed
independently by Celartem Technology Inc. At dawn of Internet
commercial use or at the time when Broadband was not widespread
like today, developers of image format for network distribution
straggled with how they could transmit data maintaining certain
quality in a small data capacity. However, the fast-paced
introduction of Broadband into communication infrastructure
substantially shifted customer demands for image technology
providing network to quality priority not quantity. Today,
such technology is utilized only in the specific field.
How to evaluate quality images, which is one of requirements
in broadband era, can be separated into two groups; the number
of Pixel (mega pixel), deciding the image size and the number
of colors, creating sophisticated images. The
idea of mega pixel or resolution when printing has been widely
accepted along with digital camera popularization. It led several companies to developing higher imaging technologies that allow
to flexibly applying to different sizes with greater resolution. In the mean time Celartem Technology focused on the facts that the number of
colors on computer games increased at high speed and that
the standard in medicals needs more than 4× the number of
colors on the computer screen for normal use. By doing so, we proudly succeeded in developing special format that makes possible
to easily apply to subtle differences in color. That innovative imaging format that is PixelLive.
PixelLive Features
- Lossless Encoding
PixelLive enables users to
encode images lossless and creates VFZ files, which keep
the quality completely lossless.
Unlike JPEG, a DCT (Discrete Cosine Transformation) base
technology, which encodes images lossy, PixelLive can maintain
quality of original image.
- Color Layered Data Structure
It is possible to select any quality level (i.e. level
1-proof level) to explore the image. Higher
quality level can explorer upon the request of users
or the Network Band Widths.
Image files saved in PixelLive format consist of six different
quality levels and each level contains 256 x 256 pixels.

- PixelLive Scaling Logic
PixelLive, an independently developed image format by Celartem
Technology Inc., uses original image scaling technology. Unlike
to other common scaling algorithm, PixelLive extracts
edges of images and scale image along edges.
Please refer to white paper, PixelLive scaling logic, for
detailed information.
- Security Control for Image
Viewing
Combined PixelLive format with PixelSafe Server or PixelSafe
SDK, security control can be archived. Resister
one file to add various security controls for image viewing
such as viewing rights, scaling size, quality level, saving
rights and adding watermark-either visible or invisible.
