Detailed Description

LPV Feature Locating Library, provides classes for classic object/edge detection tasks.

This library provides classes for classic object/edge detection tasks. To include the definitions of the library's classes, use the following directive:

Example Code

C++

#include "LPVLocate.h"

Qt Demo: QtLine, QtCircle

C#

using LPVLocateLib;

C# Demo: CSharpLine, CSharpCircle

COM

#define LPV_COM // enable COM interfaces
#include "LPVLocate.h"

MFC Demo: MFCLine, MFCCircle

Enumeration Type Documentation

LPVCircleDrawFlags

enum LPVCircleDrawFlags

This enumeration represents the flags to control the circle detection result's drawing behavior.

Enumerator
LPVCircleDrawCircle	Draw the circle
LPVCircleDrawCenter	Draw the center point of the circle
LPVCircleDrawIndex	Draw the index of the circle on its right
LPVCircleDrawDefault	Default draw flags, which draws only the circle
LPVCircleDrawAll	Draw a circle detection result with all components

LPVLineDrawFlags

enum LPVLineDrawFlags

This enumeration represents the flags to control the line detection results' drawing behavior.

Enumerator
LPVLineDrawLine	Draw the straight line
LPVLineDrawMidPoint	Draw the middle point of the line
LPVLineDrawEndPoints	Draw the end points of the line
LPVLineDrawIndex	Draw the index of the line right to its middle point
LPVLineDrawDefault	Default draw flags, which draws only the straight line
LPVLineDrawAll	Draw a line detection result with all components
