Overview

The web demo uses eVe’s visual search technology to enable users to search and retrieve images from a sample set of real data. Users can visually search on five categories of images: Clothes, Jewelry, Medical, Sunsets, and Textures.

To run the eVe demo:

Point your web browser to http://www.evisionglobal.com/tech/basic_demo.html.

Follow the onscreen instructions.

Note: We recommend you run the eVe demo before continuing with this section.

The eVe web demo is a Java servlet-based web application where servlets are used to:

• handle requests from the browser

• retrieve information from the database via the eVe API

• dynamically construct the HTML pages delivered to the client web browser
   

Java servlets on the webserver use the eVe SDK toolkit to perform the visual searches. The three main classes from the toolkit used by the Java servlets are:

• MediaCollection. Represents the database of images.

• MediaObject. Represents an image in the MediaCollection.

• SearchResults. A list of MediaObjects that satisfy the visual search criteria.

See the following section, eVe Interfaces Used in eVe Demo, for information about the eVe interfaces and methods used in the demo.
