We estimate the local  statistical texture model of a single mammogram in the form of  multivariate Gaussian mixture. The probability density is estimated  from the data obtained by pixelwise scanning of the mammogram with  the search window. In the second phase, we evaluate the estimated  density at each position of the window and display the corresponding  log-likelihood value as a gray level at the window center. Light  gray levels correspond to the typical parts of the image and the  dark values reflect unusual places. The resulting log-likelihood  image exactly correlates with the structural details of the original  mammogram, emphasizes locations of similar properties by contour  lines and may provide additional information to facilitate  diagnostic interpretation.</abstract> <abstract language="cze" primary="0">Předmětem práce je návrh diagnostického vyhodnocování screeningových mamogramů pomocí lokálního statistického modelu. Cílem metody je zvýraznění diagnosticky významných detailů mamogramu. Výsledkem zpracování je tzv. věrohodnostní obraz původního mamogramu, který by v kombinaci s původním snímkem mohl usnadnit práci radiologa.</abstract>    <reportyear>2008</reportyear>  <RIV>IN</RIV>      <permalink>http://hdl.handle.net/11104/0158711</permalink>       <arlyear>2008</arlyear>       <unknown tag="mrcbU10"> 2008 </unknown> <unknown tag="mrcbU10"> Praha ÚTIA AV ČR </unknown> </cas_special> </bibitem>
