How can I tell if a photo is forged?

Image forgery detection

1. Content-Aware Fill and PatchMatch (for copy/pasting)
2. Content-Aware Healing (for copy/pasting and splicing)
3. Clone-Stamp (for copy/pasting)
4. Seam carving (image retargeting)
5. Inpainting (image reconstruction of damaged parts — a special case of copy/pasting)
6. Alpha Matting (for splicing)

What is image forgery detection?

The pixel-based image forgery detection aims to verify the authenticity of digital images without any prior knowledge of the original image. There are many ways for tampering an image such as splicing or copy-move, resampling an image (resize, rotate, stretch), addition and removal of any object from the image.

How do you know if an image is manipulated?

11 Ways to Easily Identify Manipulated Images

1. Check the Edges. When something has been superimposed into a scene, you can sometimes tell by looking at the edges.
2. Look for Reversed Text.
3. Examine Any Shadows.
4. Missing Reflections.
5. Bad Perspective.
6. Look for Remnants of Deleted Objects.
7. Look for Signs of Cloning.
8. Try Zooming In.

What are the three types of forgery?
