In this paper, we demonstrate that the capabilities of a binary phase-only filter (BPOF) can be enhanced to identify targets irrespective of rotation, scale or the imaging spectral band by utilizing the concept of log-polar transform and image fusion

This paper reports a morphological phase-only correlation technique based on bit-map representation for recognition of color as well as grey images in a hybrid digital-optical correlation architecture. The color image is decomposed into its R, G and

Images of a target in a specific spectral band in general show no correlation with images of the same target in a different spectral band. Hence in a joint transform correlator (JTC) architecture, if the reference and input target are the images capt

Filters synthesized with images of a specific spectral band in general fail to recognize targets in a different spectral band. In this paper, we therefore demonstrate the use of the wavelet-modified maximum average correlation height (WaveMACH) filte

In this paper, we report a log-polar transform-based filter for in-plane rotation and scale-invariant target recognition. The log-polar transform is a known space-invariant image representation used in several image vision systems to eliminate the ef

A distortion invariant hybrid digital-optical correlator system is developed for automatic target recognition. A MACH filter is synthesized using a set of training images. Using this MACH filter, rotation invariance from −30° to 30° and scale inv

We implement a binary differential joint-transform correlator for real-time single- and multiple-target recognition applications. In a real-time situation the input scene is captured using a CCD or thermal camera. The obtained joint power spectrum is
