“…An important role of the parameter K is to eliminate meaningless high frequency components in stereo images. The use of limited bandwidth in inverse DFT significantly improves the matching performance, which is consistent with the spectral weighting technique employed in the conventional 2D POC-based approach [4].…”

“…In this section, we evaluate the performance of the proposed technique in terms of computational cost and accuracy. We compare four different correspondence techniques using (i) 1D BLPOC (proposed), (ii) 2D POC [4], (iii) SAD [2] and (iv) SSD [2], where each technique is equipped with sub-pixel stereo matching capability. …”

“…The authors have already developed POC-based passive 3D measurement system, whose accuracy is comparable with those of projector-based active 3D measurement systems [4]. A drawback of POC-based approach is its high computational cost in computing 2D POC function for correspondence search, which limits the potential area of applications.…”

“…By taking the average of 1D BLPOC functions, we have the overall correlation curve r K (n) with significantly improved PNR. (iii) Coarse-to-fine strategy for robust correspondence search We adopt a coarse-to-fine strategy using image pyramids for robust correspondence search [4]. In this technique, we use some coarser images of the original image.…”

This paper presents a technique for high-accuracy correspondence search between stereo images using 1D Band-Limited PhaseOnly Correlation (BLPOC). The stereo correspondence search can be reduced to 1D search through image rectification. However, we usually employ block matching with 2D rectangular image blocks for finding the best matching point. In this paper, we propose the use of 1D BLPOC instead of 2D block matching for correspondence search. The use of 1D BLPOC makes possible significant reduction in computational cost without sacrificing reconstruction accuracy. The resulting reconstruction accuracy is comparable with 2D POC-based method, and is much higher than SAD/SSD-based methods.

Abstract. This paper describes high-resolution waveform matching based on a Phase-Only Correlation (POC) technique and its application for a side-channel attack. Such attacks, such as Simple Power Analysis (SPA) and Differential Power Analysis (DPA), use a statistical analysis of signal waveforms (e.g., power traces) to reduce noise and to retrieve secret information. However, the waveform data often includes displacement errors in the measurements. The use of phase components in the discrete Fourier transforms of the waveforms makes it possible to estimate the displacements between the signal waveforms with higher resolution than the sampling resolution. The accuracy of a side-channel attack can be enhanced using this high-resolution matching method. In this paper, we demonstrate the advantages of the POC-based method in comparison with conventional approaches through experimental DPA and Differential ElectroMagnetic Analysis (DEMA) against a DES software implementation on a Z80 processor.
