## Abstract A novel feature of 2D and 3D patterns invariant to similarity transformations is derived from the bispectrum. The invariant feature is a histogram of triple products of frequency components and is calculated with the Fourier transform of original images. Computer experiments on sinusoid

## Purpose: To evaluate the ability of a prototype digital tissue recognition (dtr) system to improve the accuracy of detection of metastases on magnetic resonance (mr) images in the rabbit vx-2 tumor model. ## Materials and methods: Multiple mr imaging (mri) sequences, including pre-contrast and
