The original multispectral (MS) images obtained from multi-lens cameras (MSCs) have significant misregistration errors, which require image registration for precise spectral measurement. However, due to the nonlinearity intensity differences among MS images, performing matching is difficult find sufficient correct matches (CMs) registration, and results in a complex coarse-to-fine solution. Bas...

هدف از پژوهش حاضر ارائه روشی برای تشخیص و جداسازی تصاویر غیراخلاقی از تصاویر معمولی است. تشخیص تصاویر غیراخلاقی برای فیلتر مفاهیم نامناسب در اینترنت لازم و ضروری است. به¬خصوص در مواردی همچون فیلتر مفاهیم نامناسب در شبکه¬های اجتماعی و اشتراک¬گذاری تصویر، که از فیلتر کل سایت پرهیز می شود. تنوع در مناظر، پس¬زمینه¬ی شلوغ و نواحی غیراخلاقی کوچک در تصویر از چالش¬های این مسئله هستند. تشخیص تصاویر غیرا...

The genome of the malaria parasite Plasmodium falciparum contains the surf gene family which encodes large transmembrane proteins of unknown function. While some surf alleles appear to be expressed in sexual stages, others occur in asexual blood stage forms and may be associated to virulence-associated processes and undergo transcriptional switching. We accessed the transcription of surf genes ...

The Digital Research Infrastructure for the Arts and Humanities-project (Dariah-DE) is dedicated to evaluate information retrieval technologies for research infrastructures of social, humanand cultural studies like universities. One on of the main project-participants is the Salomon-Ludwig-Steinheim Institute of German-Jewish-History which documents Hebraic tombstones as a part of Jewish histor...

SIFT-like representations are considered as being most resistant to common deformations, although their computational burden is heavy for low-computation applications such as mobile image retrieval. H. Bay et. al. proposed an efficient implementation of SIFT called SURF. Although this descriptor has been able to represent the nature of some underlying image patterns, it is not enough to represe...
