Spectral optimized asymmetric segmented phase-only correlation filter.
We suggest a new type of optimized composite filter, i.e., the asymmetric segmented phase-only filter (ASPOF), for improving the effectiveness of a VanderLugt correlator (VLC) when used for face identification. Basically, it consists in merging several reference images after application of a specific spectral optimization method. After segmentation of the spectral filter plane to several areas,...
متن کاملSpectral Estimation for Sensor Arrays
The array processing problem is briefly discussed and an abstract spectral estimation problem is formulated. This abstract problem involves the estimation of a multi-dimensional frequency-wavevector power spectrum given certain measurements of the correlation function and knowledge of the spectral support. The pursuit of correlation-matching spectral estimates leads to the extendibility questio...
متن کاملNon-filter waveform generation from cepstrum using spectral phase reconstruction
This paper discusses non-filter waveform generation from cepstral features using spectral phase reconstruction as an alternative method to replace the conventional source-filter model in text-to-speech (TTS) systems. As the primary purpose of the use of filters is considered as producing a waveform from the desired spectrum shape, one possible alternative of the sourcefilter framework is to dir...
متن کاملThe Impact of the Spectral Filter Bandwidth on the Spectral Entanglement and Indistinguishability of Photon Pairs of SPDC Process
In this paper, we have investigated the dependence of the spectral entanglement and indistinguishability of photon pairs produced by the spontaneous parametric down-conversion (SPDC) procedure on the bandwidth of spectral filters used in the detection setup. The SPDC is a three-wave mixing process which occurs in a nonlinear crystal and generates entangled photon pairs and utilizes as one of th...
متن کاملSpectral Filter Tracking
Visual object tracking is a challenging computer vision task with numerous real-world applications. Here we propose a simple but efficient Spectral Filter Tracking (SFT) method. To characterize rotational and translation invariance of tracking targets, the candidate image region is models as a pixelwise grid graph. Instead of the conventional graph matching, we convert the tracking into a plain...
