Summary
[edit]DescriptionMakroskop (Abraham Lincoln).png |
Deutsch: Das Originalbild zeigte das bekannte Gesicht des US-Präsidenten Abraham Lincoln vom 9. Februar 1864. Dieses Originalbild von Lincoln ist in der Public Domain. Das Bild wurde dann stark verpixelt (englisch pixelated). Das verfremdete Bild besteht aus 21 mal 32 Pixeln. Je weiter man es von sich entfernt hält, desto besser erkennt man das Gesicht. Alternativ kann man auch die Augen zukneifen oder das Bild verkleinern. Alle drei Methoden passen auf die Idee eines Makroskops als Erkenntnisinstrument. Eine wissenschaftliche Beschreibung des Effektes steht im Artikel: L. D. Harmon: The recognition of faces. In: Scientific American. November 1973. Seite 75. Eine populärwissenschaftliche Erklärung steht in: Philip Johnson-Laird: Der Computer im Kopf. Formen und Verfahren des Erkennens. Deutscher Taschenbuch Verlag. 1996. ISBN: 3-423-30499-5. Dort die Seite 87. Englischer Originaltitel: The computer and the mind. 1993. Quellseite mit Text: https://www.rhetos.de/html/lex/schachbrettbild.htm |

That was quite unnecessary, because every pixel in this image is an opaque shade of gray. Corrected to Grayscale encoding (8 bits per pixel) with the help of OxiPNG and ZopfliPNG. |
