IET Science, Measurement & Technology, 2013 In partial discharge (PD) analyses, there is a need to compare the noise level of measured signals in different conditions and/or after applying certain signal processing algorithms (e.g. noise reduction). Moreover, in PD analyses through modelling approaches, whenever noisy signals should be constructed by adding noise with a desired level to the ...

Edge Detection Operators: Peak Signal to Noise Ratio Based Comparison [PDF]
International Journal of Image, Graphics and Signal Processing, 2014 Edge detection is the vital task in digital image processing. It makes the image segmentation and pattern recognition more comfort. It also helps for object detection. There are many edge detectors available for pre-processing in computer vision. But, Canny, Sobel, Laplacian of Gaussian (LoG), Robert's and Prewitt are most applied algorithms.

Hybrid Algorithm to Improve Robustness of Image Watermarking [PDF]
Engineering and Technology Journal, 2015 Watermarking is the process of embedding digital information into any multimedia data such as an image, audio or video file in such a way that intruder cannot be able to trace the signal to protect copyright of intellectual property of the owners.
