Using Spiral Scan Technique for Medical Image Watermarking with Tamper Detection and Recovery

This paper will study the spiral scan technique for Medical Image Watermarking with Tamper Detection and Recovery by Jasni Mohd Zain (2006).The spiral algorithm in clockwise and anti-clockwise direction is presented to test when the tamper is made near to the centre of image. For ultrasound ima...
