2000 Medical Imaging 2000: Image Display and Visualization  
In this work, we examine the feasibility of using MPEG-4 for coding ultrasound sequences.  ...  The basis of these new capabilities is object-based video coding, in which a video image is represented as a set of regions of interest, or video objects, that are coded independently.  ...  MPEG-4 is a new standard that extends previous MPEG standards to include support for user interaction and flexible display of multiple video bitstreams. 1,2 The basis of these new capabilities is object-based  ...

Secured Telemedicine Using Whole Image as Watermark with Tamper Localization and Recovery Capabilities

2015 Journal of Information Processing Systems  
Region of interest (ROI) is the most informative part of a medical image and mostly has been used as a major part of watermark.  ...  In region-based watermarking schemes an image region of non-interest (RONI) is the second important part of the image and is used mostly for watermark encapsulation.  ...  The image hash code was combined to the first segment; each segment was converted to binary and compressed separately to prevent the formation of binary long sequences for saving the watermark compression  ...
