Returns individual fields of a spatial map.

Combines two spatial maps.

Makes it possible to use single RemapImage filter even if there are two or more image remapping operations (e.g. lens distortion + perspective distortion).

Converts a spatial map to a different format.

Splits a spatial map into two matrices of source coordinates.

Creates a spatial map representing an image inverse polar transform.

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

Creates a spatial map representing an image resizing.

Data preprocessing for fast image resize between two constant sizes. The result is used by RemapImage.

Creates a spatial map which performs transform defined as a 3x3 homography matrix.

Creates a perspective transform map from four points denoting a rectangle in the world coordinates.

Data preprocessing for fast perspective correction. The result is used by RemapImage.

Creates a spatial map for transformations from a sphere surface to a flat rectangle.

Inspection of the surface of balls and other spherical objects. The result is used by RemapImage.

Applies a precomputed image transform, defined by a spatial map object.

Fast (precomputed) image transformations, especially for view undistortion or object geometry correction (e.g. pos recognition of labels on cylindrical bottles).

Computes locations of image point on the source image from image point location on remapped image.
