in this paper, a new method is introduced for sperm detection in microscopic images for infertility treatment. in this method, firstly a hypothesis testing function is defined to separate sperms from plasma, non-sperm semen particles and noise. then, some primary candidates are selected for sperms by watershed-based segmentation algorithm. finally, candidates are either confirmed or rejected us...

We propose a robust image enhancement algorithm dedicated for muscle fiber specimen images captured by optical microscopes. Blur or out of focus problems are prevalent in muscle images during the image acquisition stage. Traditional image deconvolution methods do not work since they assume the blur kernels are known and also produce ring artifacts. We provide a compact framework which involves ...

We devise a field theoretical formalism for a microscopic theory of nucleation processes and phase coexistence in finite dimensional glassy systems. We study disordered p-spin models with large but finite range of interaction. We work in the framework of glassy effective potential theory which in the mean field is a non-convex, two-minimum function of the overlap. We associate metastability and...

This paper presents and studies a generalization of the microscopic image reconstruction problem (MIR) introduced by Frosini Nivat (2007) (2002). Consider specimen for inspection, represented as collection points typically organized on grid in plane. Assume each point x has an associated physical value ?x, which we would like to determine. However, it might be that obtaining these values precis...

Warp and weft spacing and its coefficient of variation affect the physical properties of fabrics such as fabric hand, frictional and mechanical properties. In this paper the weft and warp spacing and its coefficient of variation for plain weave is calculated using Fourier transforms. Different methods have been used in this work including autocorrelation function. First, two dimensional power s...
