Talk:VP8 Image Analyzer

db-a7

Per discussion at Wikipedia:Fringe theories/Noticeboard#Prepare for the excrement to impact the rotational air impeller..., I have tagged this page for speedy deletion with Template:db-a7. --Guy Macon (talk) 12:44, 10 April 2021 (UTC)[reply]

Looks like I used the wrong template. "It's a product. products are not eligible for A7, just companies. Use AfD"

Meanwhile, at WP:FTN, Wdford helpfully wrote:

"The VP8 Image Analyzer was a NASA machine, which was used to create 3D images out of photos of the moon, to help analyse the topography of the moon. Some NASA guys were shroudies, and they used it on the Shroud photos. It is interesting that the VP8 images show the burnt holes in the Shroud as pyramids standing up from the flat background, and these have to be trimmed away whenever the 'miraculous 3D image' is displayed.

A two-line summary on the VP8 Image Analyzer would fit better in the Shroud of Turin article, under the 'Image analysis' sub-section."

...and I did a search and found some interesting pages about it fom shroud-related sources:

If I can find a source for the NASA claim I might be able to save the article. Googling "VP8 Image Analyzer" "Lunar" (with the quotes) finds very little. Anyone have a source that isn't about the shroud?

[1] says

"At some point in time, some journalist out there wrote erroneously that the VP-8 was used in the space program and it seems to have stuck and become part of Shroud 'mythology.' JPL had far more sophisticated technology than the VP-8."

Does anyone have any evidence from any non-shroud source that documents anything at all about Interpretation Systems or the VP-8? --Guy Macon (talk) 02:56, 11 April 2021 (UTC)[reply]

Yes. It was an analog image analyzer sold by Interpretation Systems, Incorporated (before and after computers were common). It had two main tools: 1) a density slice function that allowed the user to discriminate and assign arbitrary colors to brightness and darkness values...usually gathered from video from sometimes through digital inputs, and 2) it would display brightness values as vertical relief, rather like a large oscilloscope, and this is how the image of the Shroud of Turin appeared as vertical relief, because the staining on the shroud was a function of the distance the fabric was from the features of the face, i.e. the nose was close to the fabric and so stained the cloth more densely, whereas the hollows of the face, further away from the fabric, stained it very little.

This article probably shouldn't exist

The only sources I found that are maybe usable: Visualizing the event horizon of a black hole and (E74-10811) ERTS-1 IMAGERY INTERPRETATION N75-10538 TECHNIQUES IN THE TENNESSEE VALLEY Final Report, Sep. 1972 - Mar. .1974 (Tennessee Univ.) 2A02:1810:BCA9:3A00:798D:8968:96A9:A884 (talk) 17:09, 6 January 2023 (UTC)[reply]
