In one-class classification (OCC) tasks, only the target class (class-of-interest (CoI)) samples are well defined during training, whereas other totally absent. OCC algorithms, high dimensional data adds computational overhead apart from its intrinsic property of curse dimensionality. For learning, conventional dimensionality reduction (DR) techniques not suitable due to negligence unique stati...

Prediction method for time series of imagery data on eigen space is proposed. Although the conventional prediction method is defined on the real world space and time domains, the proposed method is defined on eigen space. Prediction accuracy of the proposed method is supposed to be superior to the conventional methods. Through experiments with time series of satellite imagery data, validity of ...

Arcus senilis is a whitish ring-shaped or bowshaped deposit in the cornea. It is recognized as a sign of hyperlipidemia and is also associated to coronary heart disease (CHD). Iridology is an alternative method to detect diseases using iris’s pattern observation. Iridologists believe that the whitish deposit on the iris is sign of heart diseases. We develop the simple and non-intrusive automati...

We investigate the error threshold for the emergence of quasispecies in the Eigen model. By mapping to an effective Hamiltonian ruled by the “imaginary-time” Schrödinger equation, a variational ansatz is proposed and applied to calculate various properties associated with the quasispecies. The variational ansatz gives correct prediction for the survival population of the wild-type sequence and ...

Following reports on a predominant loss of blue/yellow contrast sensitivity in Parkinson's disease, we revisited the physiological phenomenon of transient tritanopia. Normative data were collected from 33 healthy individuals using different colour and time combinations. Stimuli of 440 nm wavelength (blue) proved optimal, if flashed for 50 msec within the early phase of a 2 sec pause in the 600 ...

As is well known, dark adaptation in the human visual system is much slower than is recovery from darkness. We show that at high photopic luminances the situation is exactly opposite. First, we study detection thresholds for a small light flash, at various delays from decrement and increment steps in background luminance. Light adaptation is nearly complete within 100 ms after luminance decreme...

This paper introduces an efficient Eigen values based technique for online iris image compression and identification of a human including the case of identical twins. The iris image is extracted after removing the pupil, eye brow, skin and other noise disturbances from an actual image. The extracted iris image is divided into different blocks of size of 16×16. Now, Eigen values are calculated f...

Ocular malformations and visual deficits are pathognomic of fetal alcohol syndrome (FAS). However, there are no reports on retinal visual function. To determine if prenatal (human second-trimester equivalent) or prenatal plus 10 days of postnatal (human third-trimester equivalent) ethanol exposure produced scotopic and/or photopic deficits in adult hooded rats, electroretinography (ERG) was use...
