SEM images reveal intraspecific differences in egg surface properties of common nase ( <i>Chondrostoma nasus</i> L.)

Surface Reconstruction From AFM and SEM Images

Surface Approximation from Industrial SEM Images

We are currently involved in an industrial project to recover depth information from stereo image pairs retrieved using a scanning electron microscope, (SEM). Feature based approaches to stereo provide accurate disparity estimations, however the quantity of estimates recovered is small (typically 1-2% of the image). If a continuous approximation to the surface is to be reconstructed, as request...

Automated Interpretation of SEM Images

An important part of quality control in the fabrication of integrated circuit wafers involves making three-dimen sional measurements of the wafer’s surface topography. We describe a method for obtaining a dense depth map of the wafer surface from a single Scanning Electron Microscope (SEM) image. The depth map gives a complete description of the surface topography, allowing the easy calculation...

Differences in antioxidant, morphological and biochemical responses to drought stress in different cultivars of common bean (Phaseolus vulgaris L.)

Drought stress is the most common environmental stress that can significantly influence crop productivity. In this study, morphological and biochemical properties of 17 genotypes of common bean were evaluated under different levels of drought stress and the most sensitive and tolerant genotypes were identified using multivariate analysis. The results indicated that morphological and biochemical...

Egg measurement from digital images A simple tool for calculating egg shape, volume and surface area from digital images

The geometrical properties of eggs – such as volume and surface area – have uses ranging from ecological, physiological and morphological studies in birds, to predictions of chick condition in the poultry industry. Although measurements of an egg's length and breadth can be used to approximate an egg's geometry, the coefficients used in these models are specific to the original test population,...
