Reduction of the quality of the image formed by an optical system is a function of different parameters such as lens aberrations, CCD digitization errors, and the errors of system assembling. Assembling errors usually consist of two types: 1) the prism error, which is the error of non-orthogonality of the optical axis and the image plane 2) the de-centering error, which is error of not passing ...
l’orthographe se divise en deux catégories, l’orthographe lexicale et l’orthographe grammaticale, elle désigne lensemble des normes qui règlent la façon décrire dans une langue. le rôle principal d’un système d’écriture est de déplacer des unités auditives en des unités visuelles. les fonctions de la plupart des systèmes d’écritures consistent a de transcrire les sons de la langue orale et à as...
Until recently, Cryptosporidium was thought to be a single species genus. Molecular studies now showthat there are at least 10 valid species of this parasite. Among them, two morphologically identical species, C.hominis and C. parvum are the most pathogenic identified to date and share 97% of identical genomes.Post-genomic analyses is therefore necessary to explore further the...
Automated data analysis and pattern recognition techniques are the requirements of biological and proteomicsresearch studies. The analysis of proteins consists of some stages among which the analysis of two dimensionalelectrophoresis (2-DE) images is crucial. The aim of image capturing is to generate a Photostat that can be used infuture works such as image comparison. The researchers introduce...
these days, all department stores make an effort to provide their clients with valuable products in order to project the best image for them. as a result, clients’ comprehension risk will decrease and they will be more willing to repurchase. having a good image is really important for the department stores because it makes an impression on clients’ comprehension of both quality and risk. consid...
magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
The main purpose of this paper was to introduce an efficient algorithm for fault identification in fruits images. First, input image was de-noised using the combination of Block Matching and 3D filtering (BM3D) and Principle Component Analysis (PCA) model. Afterward, in order to reduce the size of images and increase the execution speed, refined Discrete Cosine Transform (DCT) algorithm was uti...
l'orient et la perse ont été au centre de l'attention des voyageurs européens qui parcouraient le monde pour connaître l'autre monde. à ce propos, l'altérité qui est l'étude de ce qui est autre et l'image que les étrangers proposent pour cet ailleurs et ces peuples, occupent une place remarquable dans la littérature. des récits de voyage, en tant que le fruit du voyageur contiennent des inf...
in solvo-hydrothermal method, xrd pattern was indicated presence of intermediate of ammonium octatmolybdate and ammonium tetramolybdate, which were changed to stble phase of ?-moo3 annealing. sem images were indicated nanoparticle with semispheical morphology and tem image was demonstrated nanoparticles with a diameter size of 25nm. also in impregnate method. the xrd pattern was shown high crys...
Impulsive noise is one of the imposed defectives degrades the quality of images. Performance of many image processing applications directly depends on the quality of the input image. Hence, it is necessary to de-noise the degraded images without losing their valuable information such as edges. In this paper we propose a method to remove impulsive noise from color images without damaging the ima...
