Stalin, Mao, Hitler, Mussolini, and many others had photographs manipulated in an attempt to rewrite history. These men understood the power of photography and that if they changed photographs they could change history. Cumbersome and time-consuming darkroom techniques were required to alter the historical record on behalf of Stalin and others. Today, powerful and low-cost digital technology has made it far easier for nearly anyone to alter digital images. And the resulting fakes are often very difficult to detect. This photographic fakery is having a significant impact in many different areas of society. Doctored photographs are appearing in tabloid and fashion magazines, government media, main-stream media, social media, fake-news, political ad campaigns, and scientific journals. The technology that can distort and manipulate digital media is developing at break-neck speeds, and it is imperative that the technology that can detect such alterations develop just as quickly. The field of photo forensics has emerged to restore some trust to photography. This short course will provide a hands-on overview of this field.
At their foundation, photo forensic techniques rely on understanding and modeling the imaging pipeline, from the interaction of light with the physical 3-D world, the refraction of light as it passes through the camera lenses, the transformation of light to electrical signals in the camera sensor, and, finally, the conversion of electrical signals into a digital image file. We will learn the underlying theory and practical implementation details of forensic techniques from each step of this imaging pipeline.
Learning Outcomes
- Review the historical and societal context for imaging forensics.
- Understand the underlying theory and practical implementation details of forensic techniques.
- Understand how to model the imaging pipeline.
- Analyze each step of a model imaging pipeline in relation to forensic techniques.
Intended Audience
Scientists, engineers, technicians, or managers who wish to learn more about digital image forensics and related processing techniques. Familiarity with imaging pipeline concepts will be helpful.
