We present a JAVA-based Interactive Progressive Local Image Transmission (IPLIT) syste for viewing large images over the bandwidth-limited WWW in 'reasonable time'. One motivation behind this research is the need for medical specialists to remotely view medical imags, in reasonable time, over the WWW. In our IPLIT system, the user employs a JAVA-based Internet browser to view and browse a low resolution image. The identification of features or regions of interest before observing those regions in detail is performed by either selecting a particular region manually via mouse or by utilizing an automatic feature-detection mode. The automatic feature-detection displays high-resolution subimages along a trajectory determined by the user-specified feature of interest. Our program handles 3D image data as a sequence of 2D images. Our IPLIT system is tested on actual MRI, CT and Ultrasound medical images obtained from the Robarts Research Institute at the University of Western Ontario, Canada. One such image was used as the test image in this paper. A few test images were borrowed from the Human Visual Project.
