Abstract:
In recent years, the mobile device demand has largely increased because of the accessibility, ubiquity and portability of such devices, which are being used not only for personal purposes but also in several applications like education, science, entertainment, commerce and industry, among others. Visualization and interaction with high definition multimedia content, like large images and videos, using mobile devices, represents a challenge because of their very limited machine resources and bandwidth. For such application, this content requires special treatment so that users can properly access and interact. In this article, it is proposed an architectural model for efficient streaming and visualization of very large images on mobile devices using the JPEG2000 standard and an adapted image transfer protocol. Results show that the introduced architecture is effective for visualizing regions of large images and presents good performance, both for transmission and decoding processes, a
llowing a simple and dynamic interaction between user and images.
