A Hybrid of Fixed-Size and Dynamic-Size Tile Algorithm for Panoramic View on Mobile Devices

摘要

Digital image is a numeric representation of a two-dimensional image. With the current digital camera technology, every mobile device is also equipped with a camera which is usually more than one megapixel in resolution. Besides, the size of the basic image is getting bigger, for example around 1.8MB to 3.4MB on iPhone4. However, the storage for mobile devices is limited. Basically, for a panoramic view with 360° horizontal representations and with its X-resolution of more than one thousand pixels, the size of the panoramic view is around 12MB without any compression. In this paper, we proposed a hybrid of fixed-size and dynamic-size tile algorithm that overcomes the storage restriction in mobile devices. In the proposed algorithm, the panoramic view is divided into tiles and only tiles of interest are shown on the mobile screen. Based on the evaluation, the amount of the time taken to load the panoramic view is faster and the display requires less bandwidth and memory.
