In recent days, the digital images are manipulated more professionally and easily via common image processing tools. This has been highly practiced in diverse applications including the surveillance systems, where the tamper detection with higher reliability is essential. A novel image tamper detection framework is designed with two major phases: fused feature extraction framework and tamper detection. The collected data are subjected to the fused feature extraction framework, where the features like adaptive speeded up robust features (SURF), Discrete Wavelet Transform (DWT) based Patched Local Vector Pattern (LVP) features, Proposed Principal Component Analysis (PCA) based Histogram of Oriented Gradients (HoG) feature and Mode Based First Digit Feature (MBFDF) are extracted. Subsequently, the extracted features are fed as the input to Optimized Convolutional Neural Network (CNN), which results in the type of tampering in the image: copy-move, splicing, noise inconsistency and double compression. To make the detection more accurate, the weights of CNN are fine-tuned by a new hybrid optimization algorithm referred as Sealion Customized Firefly algorithm (SCFF). The proposed hybrid optimization algorithm is the amalgamation of the standard Sea Lion Optimization Algorithm (SLnO) and Firefly Algorithm (FF). Finally, a comparative evaluation is made between the proposed and existing works in terms of certain performance measures as well.
