We present an algorithm for subpixel material identi cation that is invariant to the illumination and atmospheric conditions. The target material spectral re ectance is the only prior information required by the algorithm. A target material subspace model is constructed from the re ectance using an image formation model and a background subspace model is estimated directly from the image. These...
It has long been observed that smooth Brucella can dissociate into rough mutants that are cytotoxic to macrophages. However, the in vivo biological significance and/or mechanistic details of Brucella dissociation and cytotoxicity remain incomplete. In the current report, a plaque assay was developed using Brucella strains exhibiting varying degrees of cytotoxicity. Infected monolayers were obse...
The fractal geometry is the most appropriate mathematical instrument to describe the irregularity of a natural scene, by means of few effective and reliable parameters. Therefore, fractal concepts can be used to model and to identify geometrical changes occurred in areas hit by disasters. An overall framework employing fractal based models, algorithms and tools to support identification of natu...
Photoacoustic imaging (PAI) is a promising medical imaging modality which provides the resolution of Ultrasound (US) and the contrast of Optical imaging modalities. One of the most important challenges in PAI is image formation, especially in the case that a linear-array US transducer is used for data acquisition. This is due to the fact that in the linear-array scenario, there is only 60 degre...
normal 0 false false false en-us x-none fa background: regarding the importance of right diagnosis in medical applications, various methods have been exploited for processing medical images solar. the method of segmentation is used to analyze anal to miscall structures in medical imaging. objective: this study describes a new method for brain magnetic resonance image (mri) segmentation via a ...
Image segmentation is one of the most common steps in digital image processing. The area many image segmentation algorithms (e.g., thresholding, edge detection, and region growing) employed for classifying a digital image into different segments. In this connection, finding a suitable algorithm for medical image segmentation is a challenging task due to mainly the noise, low contrast, and steep...
The intermediate filament protein IFA-2 is essential for the structural integrity of the Caenorhabditis elegans epidermis. It is one of the major components of the fibrous organelle, an epidermal structure comprised of apical and basal hemidesmosomes linked by cytoplasmic intermediate filaments that serve to transmit force from the muscle to the cuticle. Mutations of IFA-2 result in epidermal f...
Ifa ́ is believed to be the foundation of Yorùbá culture. This means every aspect of Yorùbá life, including religion, philosophy, science, ideology, recreation, literature and so on has one link or another with Ifa ́. Previous works on Yorùbá philosophy have neither related Ifa ́ semiotic symbols nor elements with Ayo ̀ Ọlọ́pọ ́n nor established any connection between the two. This study examines the...
