The alteration, repackaging, and redistribution of multimedia content like image, video, audio, etc. poses a serious threat to both national security and commercial markets. Presently with the growing popularity of digital media the world is becoming smaller and smaller. That is mainly due to the internet connectivity and WWW phenomena. But the copyright protection of intellectual properties has become...
Digital media is a craze these days. With the present day Internet connectivity the world has become smaller. The copyright protections of intellectual properties have become a necessity for prevention of illegal copying and content integrity verification. Newer data hiding techniques that satisfy the requirements of imperceptibility, robustness, capacity, or data hiding rate and security of the hidden...
The proliferation of the digitized media introduces an exigent problem of security in multimedia data transmission in the network surroundings. Consequently, digital watermark technique needs to be incorporated in a digital rights management framework to address different aspects of the content supervision. The objective is to develop low power, real time, reliable and secure data hiding system that...

The explosion of the digitized media introduces a demanding problem of security in multimedia data communication in the network environment. Accordingly, digital watermarking technique needs to be integrated in a digital rights management framework to address different features of the content management. The purpose is to build up low power, real time, reliable and secure data hiding system that can...
The current paper presents a robust watermarking method for still images, which uses the similarity of discrete wavelet transform and human visual system (HVS). The proposed scheme makes the use of pixel wise masking in order to make binary watermark imperceptible to the HVS. The watermark is embedded in the perceptually significant, spatially selected detail coefficients using sub band adaptive threshold...
This paper presents an instrumentation scheme to use acoustic signal as the control signal to regulate the operation of a grinding mill. Due to the very operational nature of the grinding mill, it is not hard rather impossible to install conventional sensors like optical, temperature etc. inside the grinding mill for obtaining feedback signal which could monitor the grinding operation. Therefore,...
Abstract. Laser angioplasty has been evaluated for coronary applications since the early 1980s. Early complications of dissection, perforation and thermal injury led to a loss of enthusiasm for this technique. Recent advances in catheter development, including optimally spaced laser fibres, athermic 308nm wavelength catheters, and saline infusion techniques have produced larger laser channels, minimised...
