Performs an inverse polar transform of an image by calculating the Euclidean coordinates of the rearranged pixels in an image transformed by the polarTransform method. See the documentation for polarTransform for details on the calculation of the polar image coordinates.
Perform a polar transform of an image by calculating the polar coordinates of the pixels in an image and rearranging the pixels into a plot of angle (theta) against radius. The polar coordinates are calculated with respect to the centroid, determined by calcCentroid or the center of the image space. All transformed images will be shifted to principal axis determined by:
Displays image moments as a heat map. A inverse hyperboic sine transform is used to scale the values. If the moments are complex numbers, the absolute value is plotted.
OrthIm-class
(Package: IM) :
Class for handling continuous or discrete orthogonal moments analysis of an image
This class contains an image and all information about the image required for computing a moments analysis of the image. The object can be passed to functions to compute moments and reconstruct the image from the moments. The types of moments that can be calculated using this object are: chebyshev, krawtchouk, hahn, continuous chebyshev, legendre, and gegenbauer.
The class contains a list of images and all information required for computing the moments of the images. The images must have the same dimensions and centroid. The object has methods for computing moments and reconstructing the image from moments. Types of moments that can be calculated for this class are: generalized pseudo-zernike, fourier mellin, fourier chebyshev, radial fourier, krawtchouk, hahn, continuous chebyshev, legendre, and gegenbauer.
Image-class
(Package: IM) :
Basic class to handle image moment analysis
This class contains general information about an image, and is inherited by the "CmplxIm" and "OrthIm" classes. It contains basic utilities and object slots which are needed for both continuous complex moment analysis and discrete/continuous real orthogonal moment analysis. An object of this class can be cast to either a CmplxIm type object or a OrthIm type object.
Compute Generalized-Pseudo Zernike, Fourier-Chebyshev, Fourier-Mellin, Radial Harmonic Fourier, Dual Hahn, Discrete Chebyshev, Krawtchouk, Gegenbauer, Legendre, Chebyshev moment type of single and multiple images.
