AN OPTIMIZED CONVOLUTION NEURAL NETWORK BASED INTER-FRAME FORGERY DETECTION MODEL - A MULTI-FEATURE EXTRACTION FRAMEWORK

open access: yesICTACT Journal on Image and Video Processing, 2021
Surveillance systems are becoming pervasive throughout our daily lives, and surveillance recordings are being used as the essential evidence in criminal investigations. The authenticity of surveillance videos is tough to confirm.

Offline signature verification using classifier combination of HOG and LBP features [PDF]

open access: yes, 2011
We present an offline signature verification system based on a signature’s local histogram features. The signature is divided into zones using both the Cartesian and polar coordinate systems and two different histogram features are calculated for each ...

A PatchMatch-based Dense-field Algorithm for Video Copy-Move Detection and Localization

open access: yes, 2017
We propose a new algorithm for the reliable detection and localization of video copy-move forgeries. Discovering well crafted video copy-moves may be very difficult, especially when some uniform background is copied to occlude foreground objects.

Document Forgery Detection

open access: yesInternational Journal of Engineering and Advanced Technology, 2023
Document forgery is an increasing problem for both private companies and public administrations. It can be said to represent the loss of time and resources. There are many classical solutions to these problems such as the detection of an integrated security pattern. In such cases, it is important that we resort to forensic techniques for the detection.

Pathways and pitfalls: a qualitative study of student experiences in biomedical science education

open access: yesFEBS Open Bio, EarlyView.
Biomedical science students from underrepresented backgrounds face barriers including financial strain, disrupted laboratory access and cultural exclusion. Peer networks provide vital support when institutional systems are difficult to navigate. To create inclusive learning environments and achieve academic success, educators should blend active, hands‐

Fast copy-move forgery detection algorithm based on group SIFT

open access: yesTongxin xuebao, 2020
Aiming at the high computational complexity of the existing copy-move image forgery detection algorithm,a copy-move forgery detection algorithm based on group scale-invariant feature transform (SIFT) was proposed.Firstly,the simple linear iterative ...

Copy-Move Forgery Verification in Images Using Local Feature Extractors and Optimized Classifiers

open access: yesBig Data Mining and Analytics, 2023
Passive image forgery detection methods that identify forgeries without prior knowledge have become a key research focus. In copy-move forgery, the assailant intends to hide a portion of an image by pasting other portions of the same image. The detection

Hybrid LSTM and Encoder-Decoder Architecture for Detection of Image Forgeries

open access: yes, 2019
With advanced image journaling tools, one can easily alter the semantic meaning of an image by exploiting certain manipulation techniques such as copy-clone, object splicing, and removal, which mislead the viewers.

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated
