Detailed Description

PrintDetector implements segmentation by means of Innovatrics ISegLib library.

It is class that defines template method PrintDetector::DoDetect for various segmentation strategies.

Constructor & Destructor Documentation

Segment()

std::vector< std::shared_ptr< PrintSegment > > Segment ( const std::shared_ptr< PrintCapture > & capture )

inlinefinal

Detects segments in given image The Function scans the provided capture to locate fingers.

For each identified finger, it estimates its position on the hand by comparing the x-coordinate of the center of the finger's bounding box rectangle. As a result, the estimation may not be precise for slaps with an angle greater than 45 degrees and is not suitable for PrintCapture types other than Slap or Thumbs.

Parameters

capture

PrintCapture

Returns

slap segments

Exceptions

EnrollmentException

when ISegLib returns error
