Configuring Locator Properties - Advanced
The Advanced Properties section of the Locator tool interface provides access to advanced
Locator parameters and properties.
The Locator detects edges in the input images, then uses the edges to generate a vectorized
description of the image, called a Scene. The Locator tool generates source contours on two
coarseness levels: Outline and Detail.
Edge Detection parameters modify the quality and quantity of contours that are generated
from the input image.
Contour Detection
Contour Detection sets how the contour detection parameters are configured. For most appli-
cations, Contour Detection should be set to All Models. Custom contour detection should only
be used when the default values do not work correctly.
Custom can specify Outline Level, Detail Level, and Tracking Inertia.
l When set to All Models, the contour detection parameters are optimized by analyzing
the parameters that were used to build all the models that are currently active.
l When set to Custom, the contour detection parameters are set manually to integer
values.
The Locator process generates two levels of contours. The coarser Outline Level contour is
used to generate hypotheses of potential instances. The finer Detail Level contour is used to
confirm the hypotheses and refine the location of the instances.
For each level, coarseness values range from 1 to 16. At level 8 for example, the resolution is
8 times lower than an image at full resolution (level 1).
Outline Level
The Outline Level contour is used to rapidly identify potential instances of the
object.
l
The higher the setting, the coarser the contour resolution.
l
To improve search speed, set the Outline Level to the highest value at
which contour geometry is still distinctive and stable.
Detail Level
The Detail Level contour is used to confirm recognition and refine the position
of valid instances.
l
The higher the setting, the coarser the contour resolution.
l
For images that are not in perfect focus, better results will be obtained
