Definiens Developer 7

Definiens Developer 7 - User Guide
2 Basic Concepts
2.3 Scene
Definiens Developer loads image data as scenes, which means that each scene usually
represents one image.
A scene consists of one or more image layers or channels of one image file. When
working with a combination of different data, a scene usually contains several image
files with multiple image layers and optionally thematic layers.
A scene can include additional information related to the image content, such as
metadata, geocoding, or geo information.
Depending on the image reader or camera, a scene combines multiple views of the
same piece of reality, each of them in a separate layer. To put it simply, a scene can
include several images of the same thing, each of them providing different information.
Each scene representing one set of data used in Definiens software is managed in a
project. Thus, scenes are the combined input image data for both projects and Definiens
workspaces.
2.4 Project
In Definiens software, a project manages a scene.
A project is a wrapper for all information related to a particular scene which is the input
image data. It stores references to at least one image layer and related result information
from image analysis expressed by classified image objects. In addition, a project contains
metadata like layer aliases and unit information. Optionally, a project can enclose
thematic layers.
During creation of a project, a scene is referenced into the project. Image analysis
extracts result information from a scene and adds it to the project. This information is
expressed in classified image objects. When viewing analyzed projects you can
investigate both the input scene and the classification of image objects representing a
result.
A project is saved as a .dpr project file.
2.5 Workspace
A workspace is a container for projects, saved as .dpj file.
A workspace file contains image data references, projects, exported result values and
references to the used ruleware. Furthermore, it comprises the import and export
templates, result states, and metadata.
