Description:
Finds a certain amour of points in a list of single-precision 2D points that are the k-closest to a test point. This method searches needlePoints by computing all distances from each point cloud point and keeping a "short list".
Syntax:
public static IEnumerable<int[]> Point2fKNeighbors(
IEnumerable<Point2f> hayPoints,
IEnumerable<Point2f> needlePoints,
int amount
)
IEnumerable<Point2f> hayPoints,
IEnumerable<Point2f> needlePoints,
int amount
)
Parameters:
- hayPoints
- Type: IEnumerable<Point2f>
- A point cloud to be searched.
- needlePoints
- Type: IEnumerable<Point2f>
- Points to search for.
- amount
- Type: int
- The required amount of closest neighbors to find.
Returns:
Type: IEnumerable<int[]>
An enumerable of arrays of indices; each array contains the indices for each of the needlePts.
