Package boofcv.abst.feature.detect.line

Class HoughGradient_to_DetectLine<I extends ImageGray<I>,D extends ImageGray<D>>

java.lang.Object

boofcv.abst.feature.detect.line.HoughGradient_to_DetectLine<I,D>

All Implemented Interfaces:

DetectLine<I>

public class HoughGradient_to_DetectLine<I extends ImageGray<I>,D extends ImageGray<D>>
extends Object
implements DetectLine<I>

Converts HoughTransformGradient into DetectLine

USAGE NOTES: Blurring the image prior to processing can often improve performance. Results will not be perfect and to detect all the obvious lines in the image several false positives might be returned.
