When there are serious occlusion and illumination change, Probabilistic Occupancy Map (POM) algorithm can track six more people simultaneously with multiple video streams. The output result of foreground detection will be the available input data in POM algorithm, so the performance of a foreground detection algorithm is very important for the entire POM algorithm. Presently, Gaussian mixture model...
Nowadays, dependability is of paramount importance in modern distributed storage systems. A challenging issue to deploy a storage system with certain dependability requirements or improve existing systems' dependability is how to comprehensively and efficiently characterize the dependability of those systems. In this paper, we present a two-layer Hidden Markov Model (HMM) to characterize the dependability...
Genomic instability is one of fundamental factors in tumorigenesis and tumor progression. Many studies have demonstrated that copy-number abnormalities at the DNA level are important in the pathogenesis of cancer. Array Comparative Genomic Hybridization (aCGH), developed based on expression microarray technology, can reveal the chromosomal aberrations in segmental copy at a high-resolution. However,...
