A region of interest(ROI) algorithm in jpeg2000 coding, with accurate bitrate control in each layer, is proposed in this paper, it permits each ROI to have its individual priority by adjusting the truncating points in *** point is decided more than once for every codeblock in each layer. The algorithm rearranges the hit allocation among background and ROIs after non-ROI coding while keeping the total bitrate constant. Moreover, it supports dynamic delineation and prioritization of ROIs. The produced bitstream is fully compliant with the jpeg2000 standard *** results demonstrating the validity of the proposed approach are also presented.

Cloud Computing provides functionality for managing information data in a distributed, ubiquitous and pervasive manner supporting several platforms, systems and applications. This work presents the implementation of a mobile system that enables electronic healthcare data storage, update and retrieval using Cloud Computing. The mobile application is developed using Google's Android operating system and provides management of patient health records and medical images (supporting DICOM format and jpeg2000 coding). The developed system has been evaluated using the Amazon's S3 cloud service. This article summarizes the implementation details and presents initial results of the system in practice.
