Image Spatial Transforms
Icon | Name | Description |
---|---|---|
CreateAffineTransformMatrix | Creates affine transform matrix matrix. Return product of matrices: Translation * Rotation * Scale * Shearing. | |
CreateImagePyramid | Creates an array of images, each downsampled from the previous one. | |
CreateImagePyramid_Gauss | Creates an array of images, each downsampled from the previous, gauss-smoothed one. | |
CropImage | Reduction of the amount of image data to be stored in memory. | |
CropImageToRectangle | Usually used for creating images of individual objects, e.g. after Template Matching. | |
CropImageToRegion | Crops an image to the area of the specified region. | |
DownsampleImage | Usually 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. | |
ImageAlongArc | E.g. "Unwrapping" of object contours, so that they appear as 1D structures on the output image. | |
ImageAlongPath | E.g. "Unwrapping" of object contours, so that they appear as 1D structures on the output image. | |
ImageInversePolarTransform | Transforms an image from polar or log-polar space to euclidean space. | |
ImagePolarTransform | Transforms an image to polar or log-polar space. | |
JoinImages | Creates a single image by glueing together the two input images in horizontal or vertical direction. | |
JoinImages_OfArray | Creates a single image by glueing together many input images in horizontal or vertical direction. | |
JoinImages_OfSeries | Joining images from a line-scan camera, which produces too few lines at a time. | |
MirrorImage | Reverses the order of the input image columns or rows depending on inMirrorDirection value. | |
ResizeImage | Enlarges or shrinks an image to new dimensions. | |
ResizeImage_Relative | Resizes an image by a factor along each axis. | |
RotateImage | Rotates an image clockwise. | |
ShearImage | Image preprocessing when there are slanted objects. | |
ShrinkImageNTimes | Shrinks an image by a natural factor along each axis. | |
TransformImage | Transforms an image by the provided transformation matrix. | |
TranslateImage | E.g. camera shaking reduction. | |
TranslatePixels | Moves the pixels of the input image by the vectors specified with inVectorImage. | |
TransposeImage | Useful when operations on image columns should be replaced with operations on image rows, which are much faster due to the cache memory. | |
UncropImage | Inverse of CropImage. |
