  That seems to be the black and white one released yesterday and not the colorized version released today.

      Thanks. Is it just me, or are there lots of artifacts in the color version that aren't present in the black & white one?

        It's just you.
        • colanderman 16y ago
          Don't be snarky. There's definitely horizontal/vertical artifacts, probably from raw pixel interpolation. They're just more noticeable in the color image because the patterns are offset so they cause hue variances: http://fstutoring.com/~chris/temp/artifacts.png http://fstutoring.com/~chris/temp/artifacts.png

            What do you mean by 'raw pixel interpolation'?
            • colanderman 16y ago
              Digital imaging devices have interesting pixel patterns. A common pattern found in digital cameras is four sensors in a square grid, red/green/blue/green. Since most image formats, like PNG, assume only three channels centered on one another, the four raw pixels must be interpolated to create one "cooked" pixel. Due to reasons relating to signal processing which I'm not qualified to discuss (e.g. Nyquist limit and aliasing), a naïve sampling of these pixels can result in image artifacts such as Moiré patterns. My guess is that the artifacts I'm seeing in these images are of this type, but I could be wrong.

                Oh you mean interpolating the Bayer filter, okay. I work in this industry (digital imaging, not space) but since all color-filtered images I get to see are raw, I only see checkerboard grayscale :-)

      The really, really small crater hits on Mercury are really awesome looking. It's like not even a single, minuscule grain of dust slamming into it was missed. I wonder now if our moon has numerous, tiny craters or mostly just large ones
