Apodization of pupil with various amplitude filters have been investigated for altering the point spread function diffraction-limited optical systems' pictures objects by employing filters, such as connes and tringle filters. We shown that, different levels apodization, lower values. An observation that these give good results values apodization parameter. (FWHM) Full width at half maximum (PSF) is smaller than Airy PSF, improving performance system.

Blood cell classification is the initial process for detecting diseases; diseases can be carried if it detected at early stage. For solving such problems. Quantitative processing of digital images based on fuzzy technique applied red blood cells. There are various features consist shape, size and colour that statistical analysis (i.e. Mean, Standard Deviation, Variance, Roundness, Skewness, Kurtosis) have been extracted. The results indicated these highly signification used cells to normal...

Biometrics has received a lot of attention from the business communities and academic during last few years. It emerged as an alternative to traditional forms identification, like card IDs. Face recognition stands one most challenging modalities, since it is natural mode identification among humans. The Traditional FR methods that based on Visible Spectrum (VS) have facing challenges pose variation, object illumination, facial disguises, expression changes. Unfortunately these limitations...
