Signal-to-noise Ratios for Television Transmission
نویسندگان
چکیده
This note is concerned with the effects of random noise interference in television transmission systems. Such systems are finding increasing application in surveillance and telefactor systems. Numerous results which have been scattered throughout the literature are collected and unified. Three topics are covered: 1. The calculation of the video signal-to-noise ratio for the commonly used television transmission systems (amplitude and frequency modulation), 2. A summary of the signal-to-noise ratio definitions (including noise weighting standards) currently in use for video transmission and conversion between these definitions, and 3. A brief discussion of the subjective evaluation of television picture quality in terms of signal-to-noise ratio. Accepted for the Air Force Franklin C. Hudson Chief, Lincoln Laboratory Office

Another Method for Defuzzification Based On Characterization of Fuzzy Numbers
Here we consider approaches to the ranking of fuzzy numbers based upon the idea of associating with a fuzzy number a scalar value, its signal/noise ratios, where the signal and the noise are defined as the middle-point and the spread of each $gamma$-cut of a fuzzy number, respectively. We use the value of a as the weight of the signal/noise ratio of each $gamma$-cut of a fuzzy number to calcula...
متن کاملSecrecy of Communications in Data Transmission by Impulses with Unknown Moments of Appearance and Disappearance
We carried out a comparative analysis of the algorithms for detecting a rectangular impulse against Gaussian white noise under either authorized or unauthorized access to the transmitted data. We presupposed that for data transmission the binary communication system is used and that the useful information in the data is whether the signal is present or absent. The case is that unauthorized acce...

The true MR signal intensity extracted from noisy MR magnitude images is biased with the Rician noise caused by noise rectification in the magnitude calculation for low intensity pixels. This noise is more problematic when a quantitative analysis is performed based on the magnitude images with low SNR(<3.0). In such cases, the received signal for both the real and imaginary components will fluc...
متن کاملEstimating PSNR in High Definition H.264/AVC Video Sequences Using Artificial Neural Networks
The paper presents a video quality metric designed for the H.264/AVC codec. The metric operates directly on the encoded H.264/AVC bit stream, parses the encoding parameters and processes them using an artificial neural network. The network is designed to estimate peak signal-to-noise ratios of the video sequence frames, thus enabling computation of full reference objective quality metric values...
متن کاملA Convolutional Neural Network based on Adaptive Pooling for Classification of Noisy Images
Convolutional neural network is one of the effective methods for classifying images that performs learning using convolutional, pooling and fully-connected layers. All kinds of noise disrupt the operation of this network. Noise images reduce classification accuracy and increase convolutional neural network training time. Noise is an unwanted signal that destroys the original signal. Noise chang...
