The original ESA/Mars Express JPEG source image has a resolution of 13.7 meters per pixel or 45 feet per pixel. I than take a 24 BITMAP high resolution snapshots (Crops) of the source.
SO....I am working with images that have resolution of 13.7 meters pixel. All my images on my website have a resolution of 45 feet per pixel.
Thanks for the reply KS15. Yes, the original science data collected by the High Resoloution Stereo Camera system on Mars Express has a resolution of 13.7 m/pixel for this particular data set. No, your final images do not. HRSC takes images only in grayscale. To get the color images you're working with, three separate grayscale images (using red, green and blue filters) are combined. These individual raw images each have a resolution of about 13.7 m/pixel for this particular data set. The process of merging these images together to form the pretty public relations images you're working with has lost some image resolution. Even the large TIFF files ESA has posted are not as clear as the less-processed science data I've been posting. And then, to make things even worse, you're using as your sources the highly-compressed JPEG versions of these images. These are much smaller files to download, but they suffer from really noticeable compression artifacts.

There is absolutely no difference between a JPEG, PNG, GIFF, TIFF, or good old bitmap in visual quality.They are the SAME. I work with these formats all the time.
You can not create a true/false logic table where one image is true because its a TIFF and one image is false because its JPEG.
Enough of this highly compress JPEG nonsense...The images on my website are maximum quality JPEGs.Even medium quality JPEGs are good. I also have Lossless PNG formats.
The problem is not with your final output images. They actually have a lot more quality than they really need, and you're ending up with some huge file sizes. For most images, you won't see any significant degradation even if you save them and post them as medium-resolution JPEGs. As I mentioned above, the problem here is that your SOURCE images are highly compressed. You're then overprocessing those images and losing even more quality.
Here's a comparison of one of the images you just posted (
F190) alongside the HRSC nadir channel science data from orbit 3253. I've enlarged both images by a factor of 4 with no pixel interpolation and have cropped just a portion of the "face" to keep the image size reasonable:
KS15 Image F190 . . . . . . . . . . . . . . . . . . . . . . . . . . HRSC Image H3253_0000_ND2.IMG (Nadir channel, Orbit 3253)
I think it's pretty obvious that many more small features are visible in the original science data than are visible in your processed version of the ESA public-relations JPEG.

The MRO is a stated resolution......Much of the detail/information in both the MGS and MRO images of Cydonia have been intentionally stripped away or blurred.
So you say. For comparison, here's the same portion of the "face" as seen by the Mars Orbiter Camera on Mars Global Surveyor:
MOC Image E03-00824 (link to original)
This is a crop from the full-size, 2 m/pixel resolution image. Please show me exactly where the image detail has been intentionally stripped away or blurred in relation to the Mars Express image I posted above.
I'd post the same portion of the "face" as seen by the MRO HiRISE camera, but it won't fit on the page.
Besides, I think the resolution of HiRISE has been pretty clearly demonstrated with images like this one showing the Opportunity rover and it's tracks along the edge of Victoria crater (

Here's a prototype MER rover with some people to give you a sense of the scale:

That rover is only 2.3 meters wide and 1.6 meters long, so the MRO image clearly has better than 1 m/pixel resolution. The actual image resolution is 27 cm/pixel (10.6 in/pixel).

The face is designed or built.....All you have to do is go to the ESA/Mars Express image and look for yourself. This conclusion is my own.....But you will come to the same conclusion in time....Not only of the
face, But other artifacts of Cydonia.
I HAVE looked for myself. I see absolutely nothing in any of these images that looks even a tiny bit artificial. Neither has NASA, and neither has ESA. You're welcome to have a different opinion, but if you're going to keep posting this stuff here and making these claims, I think you owe the readers here an explanation of your evidence. Until you can do that, your claim that there's an artificial face on Mars is no different than my claim that this is a giant white bunny rabbit living in the sky:
