# DeepDream (ディープドリーム)

> Google's visualization technique repeatedly amplifies features learned by an image-recognition network, making eyes, animals and towers emerge excessively from clouds, rocks and leaves until misrecognition becomes a recursive hallucinatory surface.

- IndexStyle No.574 — https://indexstyle.org/styles/deepdream
- Kind: Technique · Family: Digital Art · Era: 2015–
- Mood: Technique, Futurity, Exhilaration
- What this family collects: Practices that treat the computer as material rather than tool, many of them imposing limits on polygons, file size or hardware and competing inside the boundary they chose.

## Defining characteristics

- Eyes and animal faces repeated across the frame
- Swirling texture multiplying along source contours
- Multi-scale repetition that reveals new figures when viewed closer
- Saturated blue, yellow and violet rolling continuously

## Best used for

- Exhibits and critical images that make machine misrecognition immediately visible
- Music video and cover imagery that keeps a source landscape beneath a multi-scale hallucination

## Composition recipe

- Typography & lettering: Add type after processing, keeping it short, bold and simple enough not to fight the detail.
- Layout & structure: Preserve the source's large composition and amplify related features at several scales to create recursion into depth.
- Material & texture: Choose layers in a trained vision model and iteratively increase their activation through gradient ascent.

## Colour

Read off the reference works below, so a direction rather than a fixed palette.

- Ground: #F0C84B
- The colour it is remembered by: #2FD5C4
- Text and outlines: #21134A

## What to avoid

It is not a swirl filter or pasted dog faces. Preserve which layer and feature were amplified and how they bind to the source.

## Application checklist

Work through this before calling a piece an application of this style.

- [ ] Visible in the piece: Eyes and animal faces repeated across the frame
- [ ] Visible in the piece: Swirling texture multiplying along source contours
- [ ] Visible in the piece: Multi-scale repetition that reveals new figures when viewed closer
- [ ] Visible in the piece: Saturated blue, yellow and violet rolling continuously
- [ ] The layout follows: Preserve the source's large composition and amplify related features at several scales to create recursion into depth.
- [ ] The lettering follows: Add type after processing, keeping it short, bold and simple enough not to fight the detail.
- [ ] The material and surface follow: Choose layers in a trained vision model and iteratively increase their activation through gradient ascent.
- [ ] The colour relation holds: #F0C84B as ground, #2FD5C4 carrying the style, #21134A for text and outlines
- [ ] At least one reference work below has been studied directly
- [ ] The caution above ("What to avoid") has been addressed
