Real-time viewing of large images based on multi-core
基于多核架构的大图像实时浏览技术

In recent years, since data acquisition equipments have been improved, a growing number of high-precision large images appear in the medical imaging, remote sensing, meteorology, archeology and other fields. These images not only provide users with detailed information, but also bring out tremendous challenge to display them interactively. We designed a scalable parallel pipeline, according to our algorithm based on proposed method of data management. Then, we design the algorithm to zoom the large image based on CUDA(compute unified device architecture) framework interactively. Our algorithm does not require any pre-processing operation, can obtain excellent real-time performance and stability, and improve the efficiency of the browser greatly.
