GANs consist of two neural networks \u2014 a generator and a discriminator. The generator is responsible for creating synthetic content, while the discriminator evaluates the realism of the generated content. Through a repetitive process, these networks &#8220;compete&#8221; with each other, leading to improvements in the generator&#8217;s ability to produce undoubted and true-looking content.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"5_Synthesis\"><\/span><strong>5. Synthesis:<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p><\/p>\n\n\n\n<p>Once the model is trained, it can be applied to generate frames or sequences for the deepfake video. During synthesis, the AI algorithm blends the facial features of the source person onto the target person&#8217;s face in the video. The goal is to make these alterations seamless and indistinguishable from authentic footage. Techniques like facial landmark detection and mesh warping are often employed to achieve a more accurate alignment of features.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"6_Post-Processing\"><\/span><strong>6.
