This paper addresses the gray-level image representation ability of the Fourier?Mellin transform (FMT) for pattern recognition, reconstruction, and image database retrieval. The main practical difficulty of the FMT lies in the accuracy and efficiency of its numerical approximation and we propose three estimations of its analytical extension. A comparison of these approximations is performed from discrete and finite-extent sets of Fourier?Mellin harmonics by means of experiments in: (i) image… 

Complete invariants for robust face recognition

Image invariant description based on local Fourier-Mellin transform

A novel approach for real-time object identification on a mobile platform that detects keypoints within a scaled pyramid-based FAST detector and then descriptors of the object of interest are computed using an Analytical Fourier-Mellin transform.

Color Fourier-Mellin descriptors for image recognition

Fractional Fourier-Radial Transform for Digital Image Recognition

The main contribution of this work is the use of the Fractional Fourier Transform to avoid, or reduce the overlap between results due to the optimal order selection for each reference image, which helps to get a higher difference between the reference images spectrum.

Euclidean Invariant Recognition of 2D Shapes Using Histograms of Magnitudes of Local Fourier-Mellin Descriptors

A system based on the VLAD machine learning method that performs Euclidean invariant recognition of 2D shapes and requires an order of magnitude less training data than comparable methods based on convolutional neural networks.

Fourier–Mellin registration of line-delineated tabular document images

A novel, locally adaptive foreground-background segmentation algorithm is introduced, based on the median filter, which eliminates the need for Blackman windowing as usually required by DFMT image registration.

A new technique is presented for quickly identifying global affine transformations applied to tabular document images, and to correct for those transformations. This technique, based on the

A Rotation, Translation, and Scale-Invariant Approach to Content-Based Image Retrieval

The signature appears to capture perceptually relevant image features, in that it allows successful database querying using example images which have been subject to arbitrary camera and subject motion, and confirms invariance to 2D rigid transformations, as well as high resilience to more general affine and projective transformations.
