Image Spatial Transforms

Select a function from the list below.

IconNameDescription
CreateAffineTransformMatrixCreates affine transform matrix matrix. Return product of matrices: Translation * Rotation * Scale * Shearing.
CreateImagePyramidCreates an array of images, each downsampled from the previous one.
CreateImagePyramid_GaussCreates an array of images, each downsampled from the previous, gauss-smoothed one.
CropImageReduction of the amount of image data to be stored in memory.
CropImageToRectangleUsually used for creating images of individual objects, e.g. after Template Matching.
CropImageToRegionCrops an image to the area of the specified region.
DownsampleImageUsually used to speed-up image analysis at the cost of reduced precision. It is internally used to implement the pyramid strategy in template matching filters.
ImageAlongArcE.g. "Unwrapping" of object contours, so that they appear as 1D structures on the output image.
ImageAlongPathE.g. "Unwrapping" of object contours, so that they appear as 1D structures on the output image.
ImageInversePolarTransformTransforms an image from polar or log-polar space to euclidean space.
ImagePolarTransformTransforms an image to polar or log-polar space.
JoinImagesCreates a single image by glueing together the two input images in horizontal or vertical direction.
JoinImages_OfArrayCreates a single image by glueing together many input images in horizontal or vertical direction.
JoinImages_OfSeriesJoining images from a line-scan camera, which produces too few lines at a time.
MirrorImageReverses the order of the input image columns or rows depending on inMirrorDirection value.
ResizeImageEnlarges or shrinks an image to new dimensions.
ResizeImage_RelativeResizes an image by a factor along each axis.
RotateImageRotates an image clockwise.
ShearImageImage preprocessing when there are slanted objects.
ShrinkImageNTimesShrinks an image by a natural factor along each axis.
TransformImageTransforms an image by the provided transformation matrix.
TranslateImageE.g. camera shaking reduction.
TranslatePixelsMoves the pixels of the input image by the vectors specified with inVectorImage.
TransposeImageUseful when operations on image columns should be replaced with operations on image rows, which are much faster due to the cache memory.
UncropImageInverse of CropImage.
