Lmxb 4 U 1820 − 30

As part of a large-scale search for coherent pulsations from LMXBs in the RXTE archive, we have completed a detailed series of searches for coherent pulsations of 4U 1820−30 — an ultracompact LMXB with a binary period of 11.4 min, located in the globular cluster NGC 6624. The short binary period implies any coherent signal would be highly accelerated, so we used phase modulation searches, orbit...

31 30 4 Experimental Results

The general problem of unsupervised textured image segmentation remains a fundamental but not entirely solved issue in image analysis. Many studies have proven that statistical model-based texture segmentation algorithms yield good results provided that the model parameters and the number of regions be known a priori. In this paper, we present an unsupervised texture segmentation method which d...
