piXserve

Overview
|
|
|
piXserve™ is a client/server application that automatically creates
a searchable index of the visual contents of media files. piXserve
"sees" the contents of digital images and videos, and stores a
description of this content in an XML database. Through a web
browser interface users can search and retrieve images and video
segments that contain visual objects that are the same or similar to
those in their query pictures. Through the
piXserve UI users can also select specific items in their query
image in order to
search just for those.
In some cases piXserve can "understand"
what the item is, and when it does the item is automatically tagged.
We call these tags "notions". A library of notions is included
in piXserve, and more are being created all the time. Notions
cover a broad range of concepts (for example: flower, car,
vegetation, sky, beach, road, map, building, face, bikini, etc.) and
allow comparisons to be made over a fairly broad appearance of the
item in the image. Users can search for images that contain
specific notions or combination of notions.
piXserve is also
able to separate out "background" and "foreground" in a still image
or individual video frame, and these parameters can be used by a
user to better formulate a search query.
piXserve can also read text that may appear in the field of view of
the image. Users can type a text string and retrieve images/video
sequences where such text appears in the image (for example, text on
the screen of a news broadcast, or text on a street sign). piXserve
can see and recognize text in complex color images and videos with
an unmatched level of accuracy in the industry.piXserve can also
facilitate the process of cataloging digital assets. For example, it
can suggest keywords that could pertain to a picture based on the
degree of similarity between the contents of that image and those
previously indexed by piXserve and for which catalog information is
already available. piXserve will help you reduce significantly the
cost and time you spend searching and cataloging photos and videos.
Key features:
- Automatic Indexing
Point piXserve to a repository of images and video and
automatically index their contents. No manual intervention or
data entry required. piXserve “sees” what is in the image and
automatically creates records that describe the shape, the
position, the size, the color, etc. of the discernable objects
in the image. Whatever is in the image is automatically indexed.
- Powerful Search
Through a web browser interface, users login to piXserve,
connect to available databases and formulate search queries to
retrieve images and specific segments of video files:
- Use an arbitrary image from user’s dektop to search for
images/video segments that contain the same or similar items
- Use the mouse to point to an
area of the query image to
indicate which specific item(s)
should be searched for.
- Browse the contents of existing databases, and use any
of those images to formulate a visual search query.
- Search images by "Notion"
- Type a text string to search pictures/videos where that
string appears in the field of view
- Perform not only simple but also complex searches
(Example: type a text string to retrieve broadcast news
segments where that word is visible on the screen, and then
use a picture to search those results and retrieve segments
where both the text string and the desired visual object(s)
are in the same frame. Use AND, OR,
and NOT operators to combine up to 6 criteria in a single
query.
- Search by file name (any text substring that appears in
the full path of the image/video file).
- Search by keyword or other external metadata, if
available.
- Suggest keywords to describe the contents of a picture
- Comprehensive Search Environment
Users can prune and save search results for future
reference. Search results can be annotated and, as they are
stored in XML format, can be easily imported in typical office
productivity applications.
- Scaleable Architecture
piXserve is a multi-threaded, J2EE
scalable application that is suitable for the most demanding
implementations.
- Web
Services API
A REST-based API package is available to
support integrations with third party applications and workflow
environments.
