AVL.CreateImageInversePolarTransformMap Method
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 )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inImageFormat | AvlNet.ImageFormat | Information about dimensions, depth and pixel type of the image. | |||
inCenter | AvlNet.Point2D | ||||
inSpaceType | AvlNet.PolarSpaceType | Method of transformation. | |||
inInterpolationMethod | AvlNet.InterpolationMethod | Bilinear | Interpolation method used in extraction of image pixel values. Default value: Bilinear. | ||
outPolarMap | AvlNet.SpatialMap | Output spatial map. |
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.
