Every new frame is a surprise for me. With the new raw frames from right MastCam downloaded some minutes before... we have a vertical panorama!
This is the little version. If you want to see the full version of the panorama, go to: http://www.ungeologoenapuros.es/wp-content...XX-Panorama.jpg It's 8 MB. Comments and suggestions are welcome! |

An other unbayered image.
There is not only Photoshop in image processing life, I'm actually using ImageJ with the "debayer" plugin, available here (scroll down). Then, in ImageJ set the image in 16bit mode. Then, go to "plugin>debayer" (you should have install it in the correct folder in order to have it in your plugin list). The best method is "R-G-R-G", set Demosaicing Algorithm to "Adaptive Smooth Hue" (I think it gives the best results). Checkbox "Display color image". Et voilà ! Save or do whatever you want with your debayered image . -------------------- |

Great images, especially the vertical panorama!
I'm puzzled why we are still seeing hue quantization in these de-Bayered images, as we did in the color JPEGs. Why would JPEG compression of the Bayer pattern produce that effect, rather than just randomly perturbing the colors? John |

Why would JPEG compression of the Bayer pattern produce that effect, rather than just randomly perturbing the colors? Since the checkerboard bright/dark appearance of the Bayer pattern in grayscale depends on the original color of the scene, various blocks can end up having different DCT frequency domain component breakdowns, but not all frequency components are quantized equally. This, I think affects the amount of pixel crosstalk. If one overlays a Bayered image over a color one, one can see the places that experience color shfts have a distinctly different checkerboard pattern feel to them. Not completely the same mechanism as banding in highly compressed color images, but I guess you can say the root cause is the same. I like this M-100 shot: -------------------- |

That vertical panorama is terrific.
I have no sense of how large the pebbles are in the foreground -- I think they may be quite tiny. We need the Mystery Man -- and maybe the Mystery Man needs a Mystery Mouse companion to show us the size of those pebbles! There are some cleat-marks in the soil midway down. What's the cleat-to-cleat distance on a MSL wheel? -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

Yes, great work Parai'
My own version (full res available by clicking the image) : And there is also a M34 pan, incomplete for now, I think. The M100 vertical pan is pretty large in vertical. Imagine now a full 360° acqured with this camera. No, my computer will die way a lot before finishing stitching only a half of the pano. A quick math : The last M34 pan was 29 006 px wide for 3635 height. This column from M100 is 14 799 px, so about 14 800 px. A little cross product : 29 006 => x 3 635 => 14 800 y => 29 006 × 14 800 / 3 635 y => 118 098 So, this will result in a panoramic of about 118 000 pixels wide !! This is HUGE ! Is there computer which can just open such a huge picture ? I pass my hand… -------------------- |

Well, well, well... turns out Registax has a DeBayer function...
Now all I have to do is work out how to get rid of the terraformed hills, and the handfuls of emeralds scattered over the ground... -------------------- |

... What's the cleat-to-cleat distance on a MSL wheel? The grousers are 15 deg apart, therefore the distance is about 6.5cm. Paolo -------------------- Disclaimer: all opinions, ideas and information included here are my own,and should not be intended to represent opinion or policy of my employer.

Here is my attempt at an anaglyph using ANT103's work and just playing around with StereoPhotoMaker. I just warped the hell out of those graphics. I see 3d but my eyes tell me they are being twisted in there sockets!
Note: It is possible that I used a medium resolution version of ANT 103's MastCam100's Graphic! The resolution could be much worse than it should be. I just clicked on the images and copied them to my clipboard. Then pasted them into IrfanView. |
