Image transforms can be simple arithmetic operations on images or complex mathematical operations which convert images from one representation to another.
Mathematical Operations include simple image arithmetic, Fourier, fast Hartley transform, Hough transform and Radon transform.
Histogram Modification include histogram equalization and adaptive histogram equalization.
Image Interpolation includes various methods for scaling, Kriging, image warping and radial aberration correction.
Image Registration is a tool for registering two 2D or 3D similar images and finding an affine transformation that can be used to convert one into the other. The operation is suitable for registering medical images of the same object.
Background Removal is a process to correct an image for non-uniform background or non-uniform illumination.
Image Rotation is a simple tool to rotate an image about its center by the specified number of degrees.
