Real-time viewing of large images based on multi-core
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.
