Parametrization of discrete sphericity in electron microscopy images

Original language description

Electron microscopy allows us to observe nanostructures of the small objects inside the biological organisms (nuclei, photosysems, membranes). The obtained images are intensity (grayscale) levels, there is no color defined in the electrons beam. The image properties (contrast, bitdepth, dynamic range, resolution, ...) are person-specific, since the experts have an individual imaging-behavior. The background and type or size of other objects vary due to biological reasons. The aim of work is to discuss the sphericity attribute of several objects for classification purposes. Usually, the very small objects are also of small amount of occupied pixels, therefore the disretization of the object borders come into acount. The classicall Hough transformation is time consuming and valid for well spherical objects. However, in the electron microscopy several types of objects are of the experimentator interrest. Therefore, the detection and classification should be based on parametrization and evaluation of the sphericity attribute. The low time burden sollution could be done be using eliptical parameters, and area to perimeter derived ratio. The three types of electron microscopy images were tested, of different biological experiments. The parametrization of the classification criteria is automaticaly evaluated via statistical description of the given electron microscopy image.
