Structure enhancement diffusion and contour extraction for electron tomography of mitochondria.
The interpretation and measurement of the architectural organization of mitochondria depend heavily upon the availability of good software tools for filtering, segmenting, extracting, measuring, and classifying the features of interest. Images of mitochondria contain many flow-like patterns and they are usually corrupted by large amounts of noise. Thus, it is necessary to enhance them by denois...
متن کاملTotal Variation Based Image and Structure Enhancement for Electron Tomography
To date, it is firmly established that mitochondrial function plays an important role in the regulation of apoptosis (programmed cell death). There is also evidence that defects in function may be related to many of the most common diseases of aging, such as Alzheimer dementia, Parkinson’s disease, type II diabetes mellitus, stroke, atherosclerotic heart disease and cancer. This belief is found...
متن کاملNonlinear Diffusion and Image Contour Enhancement
The theory of degenerate parabolic equations of the forms ut = (Φ(ux))x and vt = (Φ(v))xx is used to analyze the process of contour enhancement in image processing, based on the evolution model of Sethian and Malladi. The problem is studied in the framework of nonlinear diffusion equations. It turns out that the standard initial-value problem solved in this theory does not fit the present appli...
متن کاملCryo-electron tomography of neurospora mitochondria.
Cryo-electron tomography was used to study the structural organization of whole frozen-hydrated mitochondria from Neurospora crassa. Unlike mitochondria from many other species and tissues, in this case the cristae form a three-dimensional network of interconnected lamellae. Basically, the three-dimensional structure of ice-embedded mitochondria from this species is consistent with previous des...
متن کاملthe underlying structure of language proficiency and the proficiency level
هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
