An adaptable navigation strategy for Virtual Microscopy from mobile platforms.

Real integration of Virtual Microscopy with the pathologist service workflow requires the design of adaptable strategies for any hospital service to interact with a set of Whole Slide Images. Nowadays, mobile devices have the actual potential of supporting an online pervasive network of specialists working together. However, such devices are still very limited.

Strategies for efficient virtual microscopy in pathological samples using JPEG2000.

This paper describes the design, implementation and validation of a new strategy for efficiently browsing large microscopical images (mega-images). A mega-image is constructed by registering a sequential set of microscopic fields of view, compressed and stored in hard disk using the JPEG2000 standard (J2K). Navigation is accelerated by fully exploiting J2K properties through the introduction of a cache strategy and an optimal delivering of quality information.

Prefetching and caching strategies for remote and interactive browsing of JPEG2000 images.

This paper considers the issues of scheduling and caching JPEG2000 data in client/server interactive browsing applications, under memory and channel bandwidth constraints. It analyzes how the conveyed data have to be selected at the server and managed within the client cache so as to maximize the reactivity of the browsing application. Formally, to render the dynamic nature of the browsing session, we assume the existence of a reaction model that defines when the user launches a novel command as a function of the image quality displayed at the client.
