We have developed spectral color banding (SCAN) as a new chromosome banding technique based on spectral analysis of differentially labeled chromosome band-specific painting probes. In this study, we succeeded in displaying a multicolor banding pattern for chromosome 3, which was almost identical to the pattern obtained with the corresponding G-banding. We applied this method to metaphase cells ...

Given an ensemble of N × N random matrices with independent entries chosen from a nice probability distribution, a natural question is whether the empirical spectral measures of typical matrices converge to some limiting measure as N → ∞. It has been shown that the limiting spectral distribution for the ensemble of real symmetric matrices is a semi-circle, and that the distribution for real sym...

In this paper a new methodology for the diagnosing of skin cancer on images of dermatologic spots using image processing is presented. Currently skin cancer is one of the most frequent diseases in humans. This methodology is based on Fourier spectral analysis by using filters such as the classic, inverse and k-law nonlinear. The sample images were obtained by a medical specialist and a new spec...

The paper describes a stereoscopic system based on a multispectral camera and an LCD projector. The concept demonstrated consists in adding spectral information to threedimensional (3D) scene reconstruction. These data are provided by a multispectral camera equipped with interference filters. Before use, this system must be calibrated. This starts with a geometric calibration of the stereoscopi...

The study examined whether the benefit of deactivating stimulation sites estimated to have broad neural excitation was attributed to improved spectral resolution in cochlear implant users. The subjects' spatial neural excitation pattern was estimated by measuring low-rate detection thresholds across the array [see Zhou (2016). PLoS One 11, e0165476]. Spectral resolution, as assessed by spectral...

A mosaicked sensor is a monolithic array of many sensors, arranged in a geometric pattern. In the commercial digital color camera market, the mosaicked color filter array (CFA) technique is widely used, in which instead of using three charged coupled devices (CCDs) to capture the red, green, and blue spectral bands for each pixel, each pixel is associated with just one device covered by an opti...

Matching Short Wave InfraRed (SWIR) face images against a face gallery of color images is a very challenging task. The photometric properties of images in these two spectral bands are highly distinct. This work presents a new cross-spectral face recognition method that encodes both magnitude and phase of responses of a classic bank of Gabor filters applied to multi-spectral face images. Three l...

In this paper, we study the confounder detection problem in the linear model, where the target variable Y is predicted using its n potential causes Xn = (x1, ..., xn) T . Based on an assumption of rotation invariant generating process of the model, recent study shows that the spectral measure induced by the regression coefficient vector with respect to the covariance matrix of Xn is close to a ...

Spectral analysis considers the problem of determining (the art of recovering) the spectral content (i.e., the distribution of power over frequency) of a stationary time series from a finite set of measurements, by means of either nonparametric or parametric techniques. This paper introduces the spectral analysis problem, motivates the definition of power spectral density functions, and reviews...
