The study was conducted to learn remote sensing information extraction in alpine wetland in Maqu, Gansu. The first principle component obtained by utilizing TM multispectral data, digital elevation data, GIMMS NDVIand principal component analysis (PCA) was regarded as the classification character. The decision tree module for wetland information extraction was built through analyzing data with spatial...
This paper examines and extracts the parallelism in the AdaBoost person detection algorithm on multi-core processors. As multi-core processors become pervasive, effectively executing many threads simultaneously is crucial in harnessing the computation power. Although the application exposes many levels of parallelism, none of them delivers a satisfactory scaling performance on newest multi-core processors...
Emerging video-mining applications such as image and video retrieval and indexing will require real-time processing capabilities. A many-core architecture with 64 small, in-order, general-purpose cores as the accelerator can help meet the necessary performance goals and requirements. The key video-mining modules can achieve parallel speedups of 19times to 62times from 64 cores and get an extra 2.3times...
