Abstract  

Image tampering is now simpler than ever thanks to the explosion of digital photos and the creation of easy image modification tools. As a result, if the situation is not handled properly, major problems may arise. Many computer vision and deep learning strategies have been put out over the years to address the problem. Having said that, people can easily recognise the photographs that were used in that research. This begs the key question of how CNNs might do on more difficult samples. In this paper, we build a complex CNN network and use various machine learning algorithms to classify the images and compare the accuracies obtained by them. Its performance is also compared on two different datasets. Additionally, we assess the impact of various hyperparameters and a data augmentation strategy on classification performance. This leads to a conclusion that performance can be considerably impacted by dataset difficulty.
