A Hybrid Method for Automatic Counting of Microorganisms in Microscopic Images
Microscopic image analysis is an essential process to enable the automatic enumeration and quantitative analysis of microbial images. There are several system are available for numerating microbial growth. Some of the existing method may be inefficient to accurately count the overlapped microorganisms. Therefore, in this paper we proposed an efficient method for automatic segmentation and count...
متن کاملRaman-activated cell counting for profiling carbon dioxide fixing microorganisms.
Raman microspectroscopy is a label-free and nondestructive technique to measure the intrinsic chemical profile of single cells. The naturally weak Raman signals hampered the application of Raman spectroscopy for high-throughput measurements. Nearly all photosynthetic microorganisms contain carotenoids that are active molecules for resonance Raman at a 532 nm excitation wavelength. Hence, the ac...
متن کاملMethod for rupturing large quantities of microorganisms.
Many procedures have been described (Umbreit et al., 1957) for the mechanical rupturing of yeast and bacterial cells. These techniques vary from simple hand grinding with abrasives to the use of extrusion or high speed shaking devices. These techniques, although generally satisfactory when dealing with small quantities of cells, are unsuitable for breaking larger quantities of cells required in...
متن کاملRapid Method for Counting Reticulocytes.
Among the several labour-saving methods for counting reticulocytes reviewed by Dacie and Lewis (1963) the least laborious is the Miller count described by Brecher and Schneiderman (1950). For this method the Miller graticule, a microscope eyepiece graticule with a square of side 7 mm. with a square of one ninth the area in one corner, is used and consecutive fields are counted, reticulocytes in...
متن کاملOn Counting Polynomials of Some Nanostructures
The Omega polynomial(x) was recently proposed by Diudea, based on the length of strips in given graph G. The Sadhana polynomial has been defined to evaluate the Sadhana index of a molecular graph. The PI polynomial is another molecular descriptor. In this paper we compute these three polynomials for some infinite classes of nanostructures.
