Adaptive Methods for Video Denoising Based on the ICI, FICI, and RICI Algorithms
Tehnički Vjesnik, 2018 In various applications, reducing noise from video sequence is of crucial importance. In this paper, we have presented performance analysis of the novel video denoising method based on the relative intersection of confidence intervals (RICI) rule, and ...

A novel video noise reduction method based on PDE, adaptive grouping, and thresholding techniques
The Journal of Engineering, 2021 Undoubtedly, video block‐matching and 3D filtering (VBM3D) has achieved a significant improvement in video denoising. Nevertheless, in practice, failure to distinguish between the different noise areas, ignoring noise variances and pixel intensity, false‐

Remove Noise in Video with 3D Topological Maps [PDF]
, 2014 In this paper we present a new method for foreground masks denoising in videos. Our main idea is to consider videos as 3D images and to deal with regions in these images. Denoising is thus simply achieved by merging foreground regions corresponding to noise with background regions.

Using Noise Level to Detect Frame Repetition Forgery in Video Frame Rate Up-Conversion
Future Internet, 2018 Frame repetition (FR) is a common temporal-domain tampering operator, which is often used to increase the frame rate of video sequences. Existing methods detect FR forgery by analyzing residual variation or similarity between video frames; however, these

PRNU-Based Source Device Attribution for YouTube Videos [PDF]
Digital Investigation, March 2019, 2019 Photo Response Non-Uniformity (PRNU) is a camera imaging sensor imperfection which has earned a great interest for source device attribution of digital videos. A majority of recent researches about PRNU-based source device attribution for digital videos do not take into consideration the effects of video compression on the PRNU noise in video frames ...
