Automatic classification of aquatic microorganisms is based on the morphological features extracted from individual images. The current works their do not consider inter-class similarity and intra-class variance that causes misclassification. We are particularly interested in case where within a class occurs due to discrete visual changes microscopic In this paper, we propose account for it by ...

The effects of ash and sulfur content on the morphology particulate matter (PM) in diesel particle filter (DPF) were investigated with five different components lubricants. aggregate primary particles analyzed using transmission electron microscopy (TEM). fractal dimensions carbon calculated by box-counting method (BCM), differential (DBC), relative (RDBC) MAD-based box counting (MAD-DBC), resu...

Image enhancement is a processing on an image in order to make it more appropriate for certain applications. It is used to improve the visual effects and the clarity of image or to make the original image more conducive for computer to process. In this paper we are going to review the different image contrast enhancement techniques. Image Enhancement techniques increase the contrast of image wh...

surfactant molecules are used as interesting tools to study the structure, function and stability of proteins. protonation states of amino acids may be changed in the presence of surfactants. in this work, using experimental observations and molecular dynamic simulation, the effects of sodium dodecyl sulfate on the acid dissociation constants of tryptophan was examined. the acid–base equilibriu...

The last years have seen an increasing use of image analysis techniques in the field of biomedical imaging, in particular in microscopic imaging. The basic step for most of the image analysis techniques relies on a background image free of objects of interest, whether they are cells or histological samples, to perform further analysis, such as segmentation or mosaicing. Commonly, this image con...
