Medical image data is a central part of diagnostics in today's healthcare information systems. With the adoption cloud computing approaches sector by most health institutions, medical are now stored remotely third party servers. Privacy, safety and security needs to be guaranteed for such digital engaging encryption ensure confidentiality authentication methods authorship. Encryption watermarking techniques this domain needed completely reversible. The engaged original plain cryptographic...
Medical images stored in health information systems, cloud or other systems are of key importance. Privacy and security needs to be guaranteed for such through encryption authentication processes. Encrypted watermarked this domain needed reversible so that the plain image operated on watermarking process can fully recoverable due sensitivity data conveyed medical images. In paper, we proposed a encrypted processing technique systems. The approach is used authenticate secure Our results...
Floodplain wetlands influence the timing and magnitude of stream responses to rainfall. In managing sustaining level water resource usage in any river catchment as well when modelling hydrological processes, it is essential that role floodplain flows recognised understood. Existing studies on hydrology within Volta River basin have not adequately represented variability wetland processes their contribution sustenance flow. order quantify extent floodwater storage riparian subsequent...
Laser-induced fluorescence (LIF) combined with multivariate techniques has been used in identifying antimalarial herbal plants (AMHPs) based on their geographical origin. The AMHP samples were collected from four origins (Abrafo, Jukwa, Nfuom, and Akotokyere) the Cape Coast Metropolis, Ghana. LIF spectra data recorded samples. Utilizing techniques, a training set for first two principal components of was modeled through use K-nearest neighbor (KNN), support vector nachine (SVM), linear...
With the current emergence of biometric image data applications on devices such as smart phones, security cameras, personal computers etc, there is a need for securing templates obtained from crime scenes well before storing them in locations cloud etc. In this paper, we proposed an encryption technique collected with approach feature based technique. The was encrypted using advanced process and visual cryptography method. method engaged extracted plain used to encrypt cryptographic Analysis...
Malaria parasite, Plasmodium falciparum, uses haemoglobin in host red blood cells (RBCs) as a major source of nutrient ring and trophozoite stages. This brings about changes the morphology functional characteristics RBCs. We investigate malaria infected RBCs uninfected RBCs-ring stages using multispectral imaging technique. Four spectral bands were found to be markers for identifying RBCs: 435 nm 660 common two whiles 590 625 respectively. These four may offer potential diagnostic RBCs, well...
<p class="1Body">Malaria parasites, <em>Plasmodium falciparum</em> (<em>P.falciparum</em>) infections are taking a great toll on the lives of people worldwide, especially in developing countries. Recently, haemozoin detection using optical techniques tends to provide comparable parasite densities (PDs) estimation. We conducted feasibility studies <em>P.falciparum</em> infected blood (<em>i</em>-blood) and uninfected...
The digital image data transmission and storage in today's cyberspace has increase with privacy security concerns. Digital media collected from different sources such as surveillance systems, forensic databases, medical images are very sensitive hence concerns regarding the safe authentication of across secured unsecured communication channels needs to be addressed. This should easily used identify source, detect modification secure content well avoiding pixel loss during original recovery...
Violet diode laser-induced chlorophyll fluorescence was used in agronomical assessment (disease severity and average yield per plant). Because cassava (Manihot esculenta Crantz) is of economic importance, improved cultivars with various levels affinity for mosaic disease were investigated. Fluorescence data correlated the plant.
Laser-induced autofluorescence (LIAF), combined with multivariate techniques, has been used to discriminate a cataractous lens from healthy tissues. In this study, 405 nm and 445 were as excitation sources induce the autofluorescence. Results show higher intensity in tissues than ones. Cataractous red shift of 0.9 1.2 at excitations, respectively. Using principal component analysis (PCA), three components (PCs) gave more 99% variability for both sources. Based on PCs, Fisher’s linear...
Cataracts are the leading cause of blindness worldwide. Current methods for discriminating cataractous lenses from healthy Sprague-Dawley rats during preclinical studies based on either histopathological or clinical assessments which weakened by subjectivity. In this work, both and lens tissues were studied using multispectral imaging technique in combination with multivariate analysis. Multispectral images captured transmission, reflection scattering modes. all, five spectral bands found to...
Security of digital images in today's cyber is a major concern. Transmission compressed and uncompressed multimedia data necessary for communication between different devices. Devices screen features resolution need very efficient fast compression techniques order to maintain visual transmitted media. Robustness key consideration importance image techniques. Full recovery after challenge algorithms. It practically closely impossible most encrypted-compressed-images or...
This paper presents the Intertropical Convergence Zone (ITCZ) as possible source mechanism of medium-scale traveling ionospheric disturbances (MSTIDs) propagating to southeast direction over South American region. Using data collected by GNSS dual-frequency receivers network from January 2014 December 2019, detrended TEC maps were generated identify and characterize 144 MSTIDs southeastward low-latitude equatorial We also used images Geostationary Operational Environmental Satellite (GOES)...
An opto-digital imaging system for counting and analysing tracks on a LR-115 detector is described. One batch of track detectors was irradiated with Am-241 determined period distance linearity test another exposed to radon gas.
