More attempts at 3-d
Actually, this page is a hodge-podge, as it deals with image processing in general, as well as dimensional imaging, or 3-D. I would appreciate any feedback on the ideas addressed here, and any contributed images will be fully credited. Also, all of these images are near-focus biased. If you can't cross your eyes you won't see 3-d in these excersizes. My apologies.
Similarity Cues
The above image shows to my eye remarkable similarities between two people who are not related in any way as far as I know. One is of research engineer Baird Spalding. The other is of Professor John Yellott, (Ph.D., Stanford University)
Mathematical psychology and visual perception. URL:
Yellott.html By combining the two faces, one can almost see an animation of someone breaking into a smile. Remember: it may require you tilt your head slightly, and move back and forth to get a good lock. This collage doesn't ever really lock, so don't feel bad. My apologies to both Mr. Spalding, and Mr. Yellott.
Image processing as performed by me on the 3-D page 3-d.htm, were all done by deformations and shade-contrast inhancement. I did not retouch any image, meaning, I did not apply any shading using "air-brush", "pen" or other tools selected from PaintshopPro. I don't know for sure that the images of the Shroud, for example, were altered in any way before I got them. The images below are from the Processing
the Face on Mars pictures page at Malin
Space Science Systems.
Images page.
These are obviously the work of professionals who know much more what they are doing than I. I am not sure that there aren't numerous images which arise spontaneously in nature, but which have remarkable "artificial" characteristics. Once again, here is a better view of the Spaceborne Imaging Radar-C image of the "face next to the Great Wall"(C-HH):
This image (C-HH) in which I, at least, perceive a face is derived from a class of filtering called C-band (6cm wavelength, horizontally transmitted, horizontally received). It is perhaps easier to see the face with the images below it. There is an even better resolved image which can be downloaded from the page link above, but it isn't a genuine tiff file according to my browser, so I couldn't include it in these pages.
Here I have made what I'm seeing it more explicit. But as I said on the other 3-D page, on the left side of this, is a larger millieu of mottling from which I've been able to discern several other faces, and one over-all face.
Let me know if you get any of this. Another interesting curiousity is the fact that the China-Wall face is oriented at about the same degree (19deg?) as the Mars face. (I wish to thank JPL and NASA for the use of these images.) Return to Index|Return to 3-D Start|Return to Miscellany
