Giga-View. A distributed gigapixel image viewer controlled by mobile devices

摘要

This thesis presents Giga-View, a gigapixel image viewer controllable from mobile devices. It's design makes interaction available through a web browser and requires no software installation or high processing power from the device being used. Fulfilling the goal of high throughput and low latency, Giga-View is capable of processing an input stream with the frame rate of 60 frames per second, without any noticeable delay being built up. The amount of data being processed each second corresponds to 33600 image fragments, translated into 520MB of data. This result was achieved by the use of various caching techniques, which combined, increase performance and make the application very efficient.
