Recognition of Copy Move Forgeries in Digital Images using Hybrid Optimization and Convolutional Neural Network Algorithm

Abstract

In the modern day, protecting data against tampering is a significant task. One of the most common forms of information display has been digital photographs. Images may be exploited in a variety of contexts, including the military, security applications, intelligence areas, legal evidence, social media, and journalism. Digital picture forgeries involve altering the original images with strange patterns, which result in variability in the image's characteristics. Among the most challenging forms of image forgeries to identify is Copy Move Forgery (CMF). It occurs by copying a portion or piece of the picture and then inserting it again, but in a different place. When the actual content is unavailable, techniques for detecting fake content have been utilised in image security. This study presents a novel method for Copy Move Forgery Recognition (CMFR), which is mostly based on deep learning (DL) and hybrid optimization. The hybrid Grey Wolf Optimization and African Buffalo Optimization (GWO-ABO) using Convolution Neural Network (CNN) technique i.e., GWO-ABO-CNN is the foundation of the suggested model. The developed model extracts the features of images by convolution layers, and pooling layers; hereafter, the features are matched and detect CMF. The MICC-F220, SATs-130, and MICC-F600 datasets were three publicly accessible datasets to which this methodology has been implemented. To assess the model's efficacy, the outcomes of implementing the GWO-ABO-CNN model were contrasted with those of other approaches.

Mobility-Aware Intelligent Sampling and Improved African Buffalo Optimization-assisted Offloading in 5G-Fog Environment

“…The GW-IABO selects the fog resources to offload the computations from the IoT devices in sub-optimal regions with the aid of the fog manager. Combining the GWO algorithm with the IABO greatly enforces the optimal selection of the fog resources in a sub-optimal region for latency-sensitive tasks [31]. Figure 3 shows the overall procedure of the RAPID methodology.…”

Hearing loss classification via AlexNet and Support Vector Machine

“…Firstly, data enhancement was used to increase MRI image information to improve generalization ability. Then, CNN was used as the depth feature extractor [19,20]. Finally, Support Vector Machine (SVM) was used to divide the extracted feature information into left-sided hearing loss SNHL (LSHL), right-sided hearing loss SNHL (RSHL), and a healthy control group (HC).…”
