چکیده

As nano-micro hybrid structures start to approach biological complexity, two problems demand computational assistance: Determination of three dimensional (3D) structure suffers from ambiguity due to the 2D nature of images, and insight into the complex growth mechanisms of the structures as well as optimization of emergent properties in their multidimensional parameter spaces, both need accurate statistics, for example in order to obtain the precise shape of size distributions. Computer image recognition is now cheap, simple to customize, and can integrate with on the spot simulation and statistical analysis. We introduce these issues generally (guiding philosophy) and with examples from scanning and tunneling electron microscopy (SEM/TEM), pedagogically showing how relatively little effort can result in crucial progress in diverse fields such as connectivity analysis of particle networks for sensors, nanowire strength analysis, metallic thin film twinning dislocation analysis, and precise determination of shapes in the transformation of nano shapes during calcination.

Automated Analysis of the Mitotic Phases of Human Cells in 3D Fluorescence Microscopy Image Sequences

The evaluation of fluorescence microscopy images acquired in high-throughput cell phenotype screens constitutes a substantial bottleneck and motivates the development of automated image analysis methods. Here we introduce a computational scheme to process 3D multi-cell time-lapse images as they are produced in large-scale RNAi experiments. We describe an approach to automatically segment, track...

P-106: The Computer-Assisted Vacuolated Sperm Analysis and Zygote Quality

Background: Digital image processing and analysis are used for computer assisted evaluation of sperm morphology. Sperm head morphology has been identified as a characteristic that can be used to predict a male’s semen quality. On the other hand, zygote competence analysis is an importance tool to select embryo(s) for transfer. The aim of the present study is to determine zygote quality resulted...

Structure Sorting of Multiple Macromolecular States in Heterogeneous Cryo-EM Samples by 3D Multivariate Statistical Analysis

Heterogeneity of biological samples is usually considered a major obstacle for three-dimensional (3D) structure determination of macromolecular complexes. Heterogeneity may occur at the level of composition or conformational variability of complexes and affects most 3D structure determination methods that rely on signal averaging. Here, an approach is described that allows sorting structural st...

Cell Detection and Segmentation Using Correlation Clustering

Cell detection and segmentation in microscopy images is important for quantitative high-throughput experiments. We present a learning-based method that is applicable to different modalities and cell types, in particular to cells that appear almost transparent in the images. We first train a classifier to detect (partial) cell boundaries. The resulting predictions are used to obtain superpixels ...

I-1: Screening of Subfertile Men for Testicularlar Carcinoma In Situ by An Automated Image Analysis-Based Cytological Test of The Ejaculate

Background: Testicular cancer (TC) is usually diagnosed after manifestation of an overt tumour. Tumour formation is preceded by a pre-invasive and asymptomatic stage, carcinoma in situ (CIS) testis, except for very rare subtypes. The CIS cells are located within seminiferous tubules but can be exfoliated and detected in ejaculates with specific CIS markers. Materials and Methods: We have built ...
