Chinese Moon Photo Doctored, Crater Moved

Posted by ScuttleMonkey on Wed Dec 05, 2007 04:39 PM
from the publicity-stunts dept.
mytrip writes "A controversy over last week's photo of the lunar surface, allegedly from China's lunar spacecraft Chang'e, appears to be resolved. It's real but it isn't. An expert says the photo's resolution shows that it is of recent origin. However, for some inexplicable reason, someone on Earth edited the photo and moved a crater to a different location. 'In the week since the picture was released amid much fanfare in Beijing, there have been widespread rumors that the photo was a fake, copied from an old picture collected by a U.S. space probe. The photo from China's Chang'e 1 orbiter is clearly a higher-resolution view, with sunlight streaming from the northwest rather than the north. The mission's chief scientist, Ouyang Ziyuan, told the Beijing News that a new crater had been spotted on the Chang'e imagery — a crater that didn't appear on the US imagery. Lakdawalla determined that the crater in question wasn't exactly new — instead, it appeared to be a crater that had been moved from one spot on the picture to another spot slightly south.'"

        Which is why China is a mature fascist country as opposed to a communist country.

        see http://www.opinionjournal.com/editorial/feature.html?id=105001682 [opinionjournal.com]

        Snippet:
        China is not, as is invariably said, in transition from communism to a freer and more democratic state. It is, instead, something we have never seen before: a maturing fascist regime. This new phenomenon is hard to recognize, both because Chinese leaders continue to call themselves communists, and also because the fascist states of the first half of the 20th century were young, governed by charismatic and revolutionary leaders, and destroyed in World War II. China is anything but young, and it is governed by a third or fourth generation of leaders who are anything but charismatic.

        The current and past generations of Chinese leaders, from Deng Xiaoping to Jiang Zemin, may have scrapped the communist economic system, but they have not embraced capitalism. To be sure, the state no longer owns "the means of production." There is now private property, and, early last June, businessmen were formally admitted to the Communist Party. Profit is no longer taboo; it is actively encouraged at all levels of Chinese society, in public and private sectors. And the state is fully engaged in business enterprise, from the vast corporations owned wholly or in part by the armed forces, to others with top management and large shareholders simultaneously holding government jobs.

        This is neither socialism nor capitalism; it is the infamous "third way" of the corporate state, first institutionalized in the 1920s by the founder of fascism, Benito Mussolini, then copied by other fascists in Europe.

      Maybe someone could explain to me the implication in the article that the data is scientifically useless. If it's just a bad stitch job done back here on Earth it would seem they would still have the original data and could reperform the stitch no? Even if they don't all the data between the stitches is still good which I would imagine is probably what the real researchers use anyway.

        Here's the issue - your sense of humor is broken. Retardation is not funny - but my joke is.

        Let's hit wikipedia real quick: Today's Feng Shui schools teach that it is the ancient Chinese practice of placement and arrangement of space to achieve harmony with the environment. [wikipedia.org] Fen Shui originated in China. The picture came from China. See the connection? That my statement is absurd is what makes it funny. That Feng Shui would be banned by the Chinese government makes the joke that much funnier. This does not 'diss' (why do you diss english with this lame slang?) Taiwanese culture in the least. Taiwan doesn't even enter the picture - unless you are running around with some kind of chip on your shoulder.

        Oh and as far as our supporting Taiwan - I personally took part in operations like this [canada.com] that have been a part of Taiwan remaining free from Chinese control. But I'm wandering now - the issue is your inability to get a joke. Pointing fingers at Christians and laughing at Allah could be funny too in the right context.

      If it isn't an obvious photoshop who's to say that the US didn't manipulate their original so that they would know if someone else was using their pictures instead of making their own. I could see the U.S. doing this to see if a government said they had technology that they did not.

          Except it doesn't appear to be a correct analysis. I can easily see the difference in the lighting and composition, but there still appears to be an extra/moved crater in the Chinese photo.

          Two issues:

          1. Is it copied?
          2. What's up with the new crater?

          The analysis concluded that it's not copied, and concluded that the moved crater can be explained [planetary.org] by a mistake stitching the components together. If you look at that article, you'll note that the new image is missing a small crater in one place, and has an extra small crater a little ways away, and there's an odd indentation around it. She figured out where the seam probably was, shifted the parts a bit, and they line up perfectly.

    As per the TFA, a mistake was made stitching together 19 separate photographs to produce image of a large area of the moon that the probe could not have captured in one shot. Since each picture is taken at slightly different angle and distance from the surface, some retouching is unavoidable. Otherwise some craters will look like a weird set of arcs with different radius rather than circles. Such stretching got to slightly move some depicted object from their exact position. In fact, it is not possible to produce a flat picture of a 3D object without distortions. Just compare the size and shape of Alaska on your globe as compared to your map.

    I would assume that you can request the original mission data for serious research use instead of having to rely on newspaper clippings for science. If those images are also doctored, then we have a genuine controversy.

    The summary almost criminally neglects to include the reported reason for doing this, which is entirely legitimate:

    Often, surface features that show up on two strips of data have to be manually corrected to produce the finished image, due to subtle changes in perspective.

    "You know that there should have been seams in that image, and I just did not look for them carefully at the time," Lakdawalla told me today.


    If you've ever viewed satellite imagery, you'll recognize that the source images are not nice, ultrahigh resolution wide arc views, but instead low resolution wide arc views or high resolution narrow arc views. The 'recognizable' product that is released to a nontechnical public, such as the images used in Google Earth, are the result of post-processing including image registration, tone correction, etc. See this article [incaindia.org] on mosaicing multi-sensor images, for example.

    Surprise. Some technician made a mistake. No cookie.

    I realize that it goes against the general Slashdot commenting procedure, but read just a little before commenting on this one, please.

    1. Two photos were poorly stitched together, repeating an image of a crater on the combined photo (the crater was photographed twice).
    2. Chinese scientists miss the poor stitch job and proclaim they found a new crater.
    3. Someone else takes a close look at this "discovery" and points out the error in the stitch job.

    The crater wasn't intentionally added, it's a result of trying to align two photos, each taken from a different perspective in which the edges won't completely line up exactly.

      They not only stitched it wrong, they also retouched the merge lines making the resulting image *useless* scientifically. It is just a nice picture now that one may as well have drawn.

    It's called post-processing. You should go to the STSCI site and download some raw Hubble frames if you want to see some sources images that were "doctored" in the extreme to create those iconic images that adorn your calendars and desktops. The unprocessed frames are barely recognizable and contain huge amounts of visible noise from cosmic ray hits and all sorts of instrument artifacts.

    The Chinese screwed up mosaicking their imagery. Big deal. Now that they know how far up their ass the scientific community will be looking, I am sure they will strive for more rigor. Their desire to be a contributing member of the scientific community appears genuine to me.

      Couldn't the additional small crater seen in the Chinese photo be from an asteroid collision that occurred after the Clementine picture was taken?

      Yep, that is exactly what happened. The asteroid hit a rectangle of terrain from another spot in the old photograph and blasted it up in the air.... well of course the moon has no air but you know what I mean... and this rectangle of terrain landed intact at the new location. Quite simple and obvious really.
