DeepDream is a computer vision program created by Google which uses a convolutional neural network to find and enhance patterns in images via algorithmic pareidolia, thus creating a dreamlike hallucinogenic appearance in the deliberately over-processed images.[1][2][3]

Software

The DeepDream software, initially codenamed "Inception" after the film of the same name,[3][1][2] was developed for the ImageNet Large-Scale Visual Recognition Challenge (ILSVRC) in 2014[3] and released in July 2015. The software is designed to detect faces and other patterns in images, with the aim of automatically classifying images.[4] The software also attempts to ascertain what is happening in a picture, making attempts to form sentences which describe it.[5]

When reiterations are run to tease out the found imagery even further, a form of pareidolia results by which psychedelic and surreal images are generated algorithmically. The oft-cited resemblance of the imagery to LSD- and psilocybin-induced hallucinations is suggestive of a functional resemblance between artificial neural networks and particular layers of the visual cortex, a matter which merits further study.[6]

After Google published their techniques and made their code open source,[7] a number of tools in the form of web services, mobile applications, and desktop software appeared on the market to enabled users to transform their own photos.[8]
