The mammogram tissue textures  are  locally represented by four causal multispectral random field  models recursively evaluated for each pixel and several scales. The  segmentation part of the  algorithm is based on the underlying Gaussian mixture  model   and  starts with an over segmented initial estimation which is  adaptively modified until the optimal number of homogeneous mammogram segments is reached. The performance of the presented method is  verified on the Digital Database for Screening Mammography (DDSM) from the University of South Florida as well as extensively tested on the Prague Texture Segmentation Benchmark and compares favourably with several alternative unsupervised texture segmentation methods.</abstract> <abstract language="cze" primary="0">Článek prezentuje víceměřítkovou neřízenou metodu automatické segmentace pro rozpoznávání potenciálně rakovinných oblastí zájmu, které obsahují fibrozně-žlázovitou tkáň, z digitálních roentgenových mamogramů. Mamografické tkáňové textury jsou lokálně reprezentovány čtyřmi kauzálními modely náhodných polí rekurzivně odhadovanými pro každý pixel. Segmentační část metody je založená na gaussovském směsovém modelu. Segmentace začíná z přesegmentovaného odhadu, který se adaptivně mění, až se dosáhne optimální počet homogenních oblastí mamogramu.  Vlastnosti publikované metody jsou rozsáhle ověřovány na Digital Database for Screening Mammography (DDSM) z University of South Florida a na Prague Texture Segmentation Benchmark pomocí nejpoužívanějších segmentačních kriterií. Metoda dosahuje lepší výsledky než několik alternativních testovaných texturních segmentačních metod.</abstract>  <action target="WRD"> <ARLID>cav_un_auth*0245453</ARLID> <name>19th International Conference on Pattern Recognition</name> <place>Tampa</place> <dates>07.12.2008-11.12.2008</dates>  <country>US</country> </action>    <reportyear>2010</reportyear>  <RIV>BD</RIV>      <permalink>http://hdl.handle.net/11104/0167195</permalink>        <arlyear>2008</arlyear>       <unknown tag="mrcbU56"> pdf </unknown> <unknown tag="mrcbU63"> cav_un_epca*0317587 Proceedings of the 19th International Conference on Pattern Recognition 978-1-4244-2174-9 676 679 Los Alamitos IEEE Press 2008 </unknown> </cas_special> </bibitem>
