Method of synthesized phase objects for pattern recognition: matched filtering

Application of Vector Filtering to Pattern Recognition

In this paper, we present a new formalism, called vector filtering, which consists in transforming a sequence of vectors through a matricial filtering. This formalism allows us to unify a number of classical approaches. We also show how vector filtering can be integrated in a pattern recognition system. We then propose a new filtering, called contextual principal components (CPC), which consist...

Phase extraction pattern recognition.

Phase extraction pattern recognition is a special case of nonlinear matched filtering. The phase extraction procedure is executed on the input function's Fourier transform as well as on the filter function's Fourier transform, both of which are manipulated for correlation purposes. This novel process is examined theoretically, by computer simulations and laboratory experiments. The implementati...

A Multi-scale Local Phase Quantization plus Biomimetic Pattern Recognition Method for Sar Automatic Target Recognition

Synthetic aperture radar (SAR) automatic target recognition (ATR) has been receiving more and more attention in the past two decades. But the problem of how to overcome SAR target ambiguities and azimuth angle variations has still left unsolved. In this paper, a multi-scale local phase quantization plus biomimetic pattern recognition (BPR) method is presented to solve these two difficulties. By...

Spatial Pattern Templates for Recognition of Objects with Regular Structure

We propose a method for semantic parsing of images with regular structure. The structured objects are modeled in a densely connected CRF. The paper describes how to embody specific spatial relations in a representation called Spatial Pattern Templates (SPT), which allows us to capture regularity constraints of alignment and equal spacing in pairwise and ternary potentials. Assuming the input im...
