Pre-processing and post-processing algorithms improve on the performance of a video compression system especially by removing spurious noise and insignificant features from the original video data. So that this will increases compression efficiency, attenuates coding artifacts and mainly improving the quality of Video data. And more over existing video compression standards like MPEG, H.26x series...
This paper proposes a steganography method using the digital images. Here, we are embedding the data which is to be secured into the digital image. Human Visual System proved that the changes in the image edges are insensitive to human eyes. Therefore we are using edge detection method in steganography to increase data hiding capacity by embedding more data in these edge pixels. So, if we can increase...
This paper proposes post processing algorithm by employing modified adaptive (method or technique) in loop deblocking filter for VP8 and Image codec's, mainly because blocking artifact is one of the most annoying artifact especially in video and image compression coding. The method proposed improves the quality of the reconstructed image and as well as video. In this paper, we have introduced deblocking...
We report on a comprehensive modeling of small diameter (<; 4 nm) nanowire field effect transistors as switches. The SPICE simulation of the transistor takes data from device and material simulations, and therefore allows for significant flexibility in tool development for nano-devices and circuits. Device simulations involve solving self-consistently the drift-diffusion equation, with Gauss Law...
Blood is a vital but often scarce resource in developing countries. It is crucial that safe blood is made available for transfusions in hospitals and clinics to prevent the spread of transfusion-transmitted infections (TTI) such as HIV, hepatitis and syphilis. We present a system designed to promote hemovigilance in developing countries by monitoring the collection and usage patterns of blood, predicting...
