The underwater images usually suffers from non-uniform lighting, low contrast, blur and diminished colors. In this paper, we proposed an image based preprocessing technique to enhance the quality of the underwater images. The proposed technique comprises a combination of four filters such as homomorphic filtering, wavelet denoising, bilateral filter and contrast equalization. These filters are ...

Two paper strips, each containing different antimicrobial agents, were placed on plates on Mueller-Hinton agar to permit antibiotic to enter the agar. A filter membrane was placed on this plate, and the microorganisms were planted on the membrane. After 6 h of incubation at 37 C, the membrane was transferred to antibiotic-free Mueller-Hinton agar containing triphenyltetrazolium hydrochloride an...

waterborne outbreaks of pathogenic bacteria from contaminated water are serious threats forpublic health. coliform bacteria have been regarded as one of the most important indicators for monitoringpathogenic bacteria. to address potential pathogenic bacterial outbreaks, the distribution and diversity ofcoliform bacteria in jiahe river, which flows through densely-populated urban area in china, ...

Abstract Laminarin is a low-molecular-weight polysaccharide found in seaweed (kelp), often equal concentrations to that the commercially important hydrocolloid alginate. However, while alginate can be easily recovered by dissolution followed acid precipitation, for laminarin, there no such straightforward way of recovering it. used as dietary fiber and, if efficiently extracted, it may function...

A CMOS switched-current adaptive filter architecture is presented. It is basically a finite impulse response (FIR) transversal filter adapted by using the Least-Mean-Square (LMS) adaptation algorithm. The design is based on delay and multiply-accumulator blocks. The implemented system can be switched to work either as an adaptive filter or as an FIR programmable filter. The adaptation signal ca...

Most e-mail readers spend a significant amount of time regularly deleting junk e-mail (spam) messages, which are a part of marketing campaigning efforts of various companies wherein users normally signed in and it also results in increasing volume of storage space and consumes network bandwidth. A challenge, therefore, rests with the developers and improvement of automatic classifiers that can ...

We propose a novel human face recognition approach in this paper, based on two-dimensional Gabor filtering and supervised classification. The feature extraction technique proposed in this article uses 2D Gabor filter banks and produces robust 3D face feature vectors. A supervised classifier, using minimum average distances, is developed for these vectors. The recognition process is completed by...
