Generated image detection

A computer program which, when run on a computer, causes the computer to carry out a method comprising:

• loading an input image;
• inputting the input image and a representation describing the input image into a denoising model for denoising the input image using the representation;
• generating a denoised image embedding from the denoised image;
• generating an input image embedding from the input image;
• comparing a difference between the input image embedding and the denoised image embedding with a similarity decision threshold to determine whether the input image is a real image or a computer generated image.

An information processing apparatus for detecting computer generated images comprising a memory and a processor connected to the memory, wherein the processor is configured to:

• load an input image;
• input the input image and a representation describing the input image into a denoising model for denoising the input image using the representation;
• generate a denoised image embedding from the denoised image;
• generate an input image embedding from the input image;
• compare a difference between the input image embedding and the denoised image embedding with a similarity decision threshold to determine whether the input image is a real image or a computer generated image.
