CreateImagePolarTransformMap


Creates a spatial map representing an image polar transform.

Name Type Description
inImageFormat ImageFormat Information about dimensions, depth and pixel type of the image
inCenter Point2D
inSpaceType PolarSpaceType Method of transformation
inInterpolationMethod InterpolationMethod Interpolation method used in extraction of image pixel values
outPolarMap SpatialMap Output spatial map
outOutputRegion Region Pixels set by the spatial map application

Applications

Data preprocessing for fast image polar transform. The result is used by RemapImage.

Description

The operation generates map that describes image transformation to polar or log-polar 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 ImagePolarTransform. For more information see ImagePolarTransform.

Complexity Level

This filter is available on Advanced Complexity Level.
