AVL.CreateImageInversePolarTransformMap(AvlNet.ImageFormat, AvlNet.Point2D, AvlNet.PolarSpaceType, AvlNet.InterpolationMethod, AvlNet.SpatialMap, AvlNet.Region)

Creates a spatial map representing an image inverse polar transform.

Namespace:AvlNet
Assembly:AVL.NET.dll

Syntax


public static void CreateImageInversePolarTransformMap(
	AvlNet.ImageFormat inImageFormat,
	AvlNet.Point2D inCenter,
	AvlNet.PolarSpaceType inSpaceType,
	AvlNet.InterpolationMethod inInterpolationMethod,
	out AvlNet.SpatialMap outPolarMap,
	out AvlNet.Region outOutputRegion
)

Parameters

inImageFormat
Type: AvlNet.ImageFormat
Information about dimensions, depth and pixel type of the image
inCenter
Type: AvlNet.Point2D
inSpaceType
Type: AvlNet.PolarSpaceType
Method of transformation
inInterpolationMethod
Type: AvlNet.InterpolationMethod
Interpolation method used in extraction of image pixel values
outPolarMap
Type: AvlNet.SpatialMap
Output spatial map
outOutputRegion
Type: AvlNet.Region

Description

The operation generates map that describes image transformation from polar or log-polar space to euclidean space. Two modes of pixel interpolation are available, the bilinear filtering being more precise and computationally expensive. Usually creating map and then using RemapImage is faster than ImageInversePolarTransform. For more information see ImageInversePolarTransform.
