The paper presents a spatial pooling technique for image quality assessment (IQA) that is based on the idea that the adaptive mechanisms of luminance and contrast in the early vision operate independently. The work is motivated by recent vision science studies on this topic that have not been investigated yet in the field of IQA. The Structural SIMilarity index (SSIM) has been selected as the base...
Based on the orthogonal projection approach, a few closed-loop subspace identification methods have been developed recently in the literature. To guarantee consistent estimation of these methods against measurement noise, this paper analyzes the rank condition for performing the corresponding singular value decomposition (SVD) involved in deriving the extended observability matrix and the lower triangular...
This paper proposes an online fault detection method for induction motors using frequency-domain independent component analysis. Frequency-domain results, which are obtained by applying Fast Fourier Transform (FFT) to measured stator current time-domain waveforms, are analyzed with the aim of extracting frequency signatures of healthy and faulty motors with broken rotor-bar or bearing problem. Independent...
In semiconductor manufacturing processes, mixed-products are usually fabricated on the same set of process tool with different recipes. Run-to-run controllers which based on the exponential weighted moving average (EWMA) statistic are probably the most frequently used in industry for the quality control of certain semiconductor manufacturing process steps. However, for mixed-product drifting process,...
This paper addresses the problem of threedimensional reconstruction and how the geometry of the stereo vision system affects the quality of such a reconstruction. We have considered the general case of non calibrated cameras with approximately known intrinsic parameters. The latter could be known either from previous experiments or from the manufacturer's specifications. In particular, the paper aims...
