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 ...

Is there a relationship between peak‐signal‐to‐noise ratio and structural similarity index measure?
In this study, the authors analyse two well‐known image quality metrics, peak‐signal‐to‐noise ratio (PSNR) as well as structural similarity index measure (SSIM), and the authors derive an analytical relationship between them which works for some kinds of common image degradations such as Gaussian blur, additive Gaussian noise, Jpeg and Jpeg2000 ...

Image matching using peak signal-to-noise ratio-based occlusion detection
A new identification mechanism is introduced for the purpose of locating objects partially occluded under low peak signal-to-noise ratio (PSNR) environment in two-dimensional grey scale image.The proposed occlusion detection is based on the utilisation of the fact that the higher the PSNR, the less the impairment of the image.

An adaptive bitonic filtering based edge fusion algorithm for Gaussian denoising
It is broadly recognized that conserving the essential geometrical features of an image is crucial while denoising it. To accomplish this aim, various denoising techniques have been represented in the literature.

Towards No-Reference of Peak Signal to Noise Ratio [PDF]
El objetivo de este trabajo es definir un estimador de calidad de imagen perceptual no referenciado aplicando los conceptos perceptuales del Modelo de Inducción Cromática. El enfoque consiste en comparar la imagen recibida, presumiblemente degradada, con las versiones perceptuales (diferentes distancias) de esta imagen degradada por medio de un Modelo ...

Hybrid Algorithm to Improve Robustness of Image Watermarking [PDF]
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.
