Answers.Body: <p>Setting aside the dubious nature of subliminal messages. You have to clearly define what subliminal is. In all your cases presented, a manual algorithmic approach would be better. An ANN would tend to average out the subliminal messages as noise, just as your brain would. In the case of #2, #3, it's a matter of contrast, in which case computer vision methods of bringing out low contrast details to the forefront combined with a manual algorithm (perhaps an OCR pass for content not expected to have text) would be the way to go. ANN are not magic bullets, and still need to be used appropriately. </p>

Answers.Text: @noviceFedora, sort of. There is research showing some effect, but minor and not toward anything a person wasn't already feeling actionable towards. Subliminal messaging effects have been exaggerated just like the effects of hypnotizing. All research I've ever read shows the brain keeps it's hold on the individual, and any attempt to influence them beyond surface level fails. Thus, it's dubious nature, refers to it's exaggerated impact, and thus a likelihood of exaggerated worry about the issue.

The things you read online about microwave induced auditory hallucinations are greatly exaggerated. In reality, such a thing is hard to control anywhere near that level, from a fundamental physics perspective.
