Source camera identification using SPN with PRNU estimation and enhancement
TL;DR: This work analyzes the PRNU estimation and enhances the content of the PRnU for better accurate identification of the source camera in sensor pattern noise associated with digital images.
Proceedings ArticleDOI
Copy Move Forgery using Hu's Invariant Moments and Log-Polar Transformations
K Tejas,C Swathi,M Rajesh Kumar +2 more
TL;DR: Huang et al. as mentioned in this paper proposed a novel algorithm that recognizes a unique approach of using Hu's Invariant Moments and Log-polar Transformations to reduce feature vector dimension to one feature per block simultaneously detecting CMF among genuine similar objects in an image.
Book ChapterDOI
Implementation of Neural Network and Feature Extraction to Classify ECG Signals
TL;DR: In this article, Pan Tompkins algorithm is used for feature extraction on electrocardiography (ECG) signals, while neural networks help in detection and classification of the signal into four cardiac diseases: Sleep Apnea, Arrhythmia, Supraventricular Arrhythmmia and Long-Term Atrial Fibrillation (AF) and normal heart beat.
Proceedings ArticleDOI
Handwritten Character Recognition Using Unique Feature Extraction Technique
TL;DR: In this article, a feature extraction technique which is a combination of unique features of geometric, zone-based hybrid, gradient features extraction approaches and three different neural networks namely the Multilayer Perceptron network using Backpropagation algorithm (MLP BP), the multilayer perceptron networks using Levenberg-Marquardt algorithm(MLP LM) and the Convolutional neural network (CNN) which have been implemented along with the Minimum Distance Classifier (MDC).
Proceedings ArticleDOI
High capacity, secure (n, n/8) multi secret image sharing scheme with security key
TL;DR: A novel algorithm to increase the sharing capacity by using (n, n/8) multi secret sharing scheme with increased security by generating unique security key which makes the secret image invulnerable to the hackers.
