Curiosity: Potential Anomalies (2015)

a reply to: MarioOnTheFly

Sanitation Mario , I must have gone on about it a few times now in last years thread, but it maybe that, before we get to see the images certain things are removed beforehand, sometimes I look at the pictures and they strike me as odd . for example , is it me or has mount sharp been stuck in a sandstorm for the last six months? maybe it just that time of year

I also get the impression sometimes ,a cloning or masking tools used , shadows that seem off ,out of place, wrong and sand banks that look unrealistic in their environment.

the terrible quality of the pictures would help in this process after jpg compression has its way, helping to obscure any alterations. a trick I use to blend photos together once their balanced, the recompression helps to give the elements comprised, a feel of unity within the photo

the moon ? defo

Some people wanted high resolution colour photos, now they have them, with all the bad side effects.

Also, the compression problems are not that big, except when people resize the images to 500% or more.

Yes, I used that trick once to hide the changes I had made on a photo, but to hide something that was already a JPEG with JPEG compression you have to add more compression, so if the photo looks the same as all other photos it's not very likely that it was recompressed.

First a mutant worm, then a giant rat, and now a man and letters drawn in a rock:

Interesting look-alikey, complete with a ballcap. Hopefully you're not saying that these things were carved into the rock by a Martian who could only draw stick-figure humans. If so...rocks. If not, nice finds!

funbox: that pic of "you" in a spacesuit should be given some kind of award.

they have another satellite up there now , they can borrow some bandwidth off the Indians , of which it seems , considering the amount of pictures they have released , already have been.

my apologies , im making no sense from this

I was not talking about bandwidth for transmitting the photos back to Earth, I was thinking about the fact that a colour photos takes around three times as much storage space as a greyscale photo of the same size, so, to they have the need of more compression than if they had only geyscale photos to store and send.

my apologies , im making no sense from this

What I meant is that if you use a JPEG image and save it again with the same compression level there will be no changes in the compression artefacts, if you want to hide something with the compression artefacts you have to use a higher compression level than the one used on the original images.

Does it make sense?

a reply to: ArMaP

it does , but how is it relevant ? nasa's camera's take a rawfile , **************************, and compresses it to jpg onboard/ , then sends it on up to the sats, who presumably have a 1 gig hardrive , then sent on over to earth and its sats , then up to the web ..

so what's with overlaying jpgs to hide jpg compression?? , what im saying is that things like cutmarks , blurs , blending marks, false horizons , added removed etc etc can be disguised by low quality compression .

interesting stuff , did you notice just above ?

a reply to: funbox

As I have said before, I have a hard time understanding most of what you write, are you saying that all those hypothetical alterations are done by the rover before sending the images back to Earth?

a reply to: ArMaP

no worries , but I do not think that these alterations would be done by a human hand , a programme of a sophisticated nature we have only ever seen in movies and books would, I expect, be more suited to this job,

either that or there's a lab on mars processing them by a herd of alien sweatshopers's

Your'e not the first person with that idea, but, being a programmer that has been working with digital images for more than 20 years I doubt things are that advanced and that the rover's computers have enough power for something like that.

You just have to look at the automated tools on Photoshop to see that they cannot fool anyone.

Maybe we'll get a photo of an alien demonstration against the bad work conditions.

Someone should post a thread on this and that sphinx looking thing. I bet alot of other members that dont visit this thread would like to see those.

a reply to: alienjuggalo

maybe they would, but be warned , spin off threads usually end up binned

nope im not , but then saying there are not computer powerfull enough to handle vast amounts of data intelligently , open up the question on how the nsa is monitoring communications , a mind buggering throughput of information as no doubt you are well aware.

i don't understand your meaning

what ?, you mean like the 'alien interview' video ?

I don't remember seeing any sign of a layer being changed by any other thing besides erosion.

I think that something a bit more sudden than erosion caused this to happen. I could be wrong.

mars.jpl.nasa.gov...

This just fascinates because in this picture I dont see one stick figure holding something I see 2 stick figures




1 is easy to pass off as just something weird and natural or Pareidolia but 2 is alot harder to explain IMO.

a reply to: alienjuggalo

And the one on the left can also be seen as, taking the entire rock into consideration, as either a stone blob-thing wearing glasses and drooling out of the right side of its mouth, or a sphinx wearing glasses and drooling out of the right side of its mouth. And those are only two other perspectives out of hundreds (if we're talking about the stick figure alone, it's obviously Sherlock Holmes carrying a Holmes-worthy magnifying glass).

That's not what I said, I specifically said the rover's computers. After all, weren't you talking about the images being processed by the rovers?

i don't understand your meaning

I mean that that automated clone tool (I don't remember the tool's name) they presented some years ago as an easy way to do things like remove footprints on the sand or leaves on the grass behind a bench (if I'm not mistaken those were the examples on the presentation video) may be good to do a simple work, but, even with a human telling it what to replace, it fails many times while covering the area we want to change and leaves many signs of cloning.

For a tool like that to work in a good enough way to fool all the people looking at the photos they would need an excellent way of detecting the things they wanted to change and an excellent way of changing them, no amount of (excusable) JPEG compression can be guaranteed to hide every thing.

I do beg you're pardon, my mistake,it's not like me to misunderstand then misconstrue intended meaning

if you look back you may notice a whole cluster of *************. this is the hypothetical stage ,in the hypothetical scenario I was envisaging , when asked about the pictures by Mario

but ill warrant there's something more special than a 486 in it

have the specs at hand ?

healing brush ? clone brush ? spot healing brush ? ? , patch tool ? , content aware move tool?

yes it would need some sophisticated piece of Ai to be aware of it's surroundings, but I do believe the Rover has some interesting gadgetry for self navigation ?

makes me wonder about the whole landing operation , many variables ide expect in such a dramatic entry, might need some exceptionally quick readjustments /reactions,, etc but then , ill bet their all ninjas at NASA control 225,300,000 km away,

feel free to enlighten

As strange as it may sound, I didn't have any problem understanding that part, that's why I talked about the processing being done by the rover.

Yes, but not as much as most people may think.

It has a RAD750 CPU, capable of >400 Dhrystone 2.1 MIPS at 200 MHz, while an old Pentium Pro is capable of 541 MIPS also at 200 MHz.

This is the easiest to find.

"Content aware" something, but I don't think it was "move".

Self navigation is much easier than recognising things that should not appear on a photo and change the photo accordingly.

The landing, although with its own challenges, it was also much easier from an AI point of view than recognising things (that, for it to work, have to have a broad definition) and changing the images.
