"Yogi" is a meter-size rock about 5 meters northwest of the Mars Pathfinder lander and was the second rock visited by the Sojourner Rovers alpha proton X-ray spectrometer (APXS) instrument. This mosaic shows super resolution techniques applied to the second APXS target rock, which was poorly illuminated in the rovers forward camera view taken before the instrument was deployed. Super resolution was applied to help to address questions about the texture of this rock and what it might tell us about its mode of origin. This mosaic of Yogi was produced by combining four "Super Pan" frames taken with the IMP camera. This composite color mosaic consists of 7 frames from the right eye, taken with different color filters that were enlarged by 500% and then co-added using Adobe Photoshop to produce, in effect, a super-resolution panchromatic frame that is sharper than an individual frame would be. This panchromatic frame was then colorized with the red, green, and blue filtered images from the same sequence. The color balance was adjusted to approximate the true color of Mars. Shadows were processed separately from the rest of the rock and combined with the rest of the scene to bring out details in the shadow of Yogi that would be too dark to view at the same time as the sunlit surfaces. This resulted in the unusual color fringing at the edges of the shadow. Image processing and mosaic by Tim Parker, JPL. |
"Mini Matterhorn" is a 3/4 meter rock immediately east-southeast of the Mars Pathfinder lander. This trio of images shows how super resolution techniques can be applied to near field targets to help to address questions about the texture of the rocks at the landing site and what it might tell us about their modes of origin. The first image shows a "raw," standard-resolution color frame of the rock. The second and third views of Mini Matterhorn were produced by combining the "Super pan" frames from the IMP camera. The composite color frame consists of 7 frames from the right eye, taken with different color filters that were enlarged by 500% and then co-added using Adobe Photoshop to produce, in effect, a super-resolution panchromatic frame that is sharper than an individual frame would be. This panchromatic frame was then colorized with the red, green, and blue filtered images from the same sequence. The color balance was adjusted to approximate the true color of Mars. The anaglyph view of Mini Matterhorn was produced by combining the left and right eye frames by assigning the left eye view to the red color plane and the right eye view to the green and blue color planes (cyan), to produce a stereo anaglyph mosaic. This mosaic can be viewed in 3-D on your computer monitor or in color print form by wearing red-blue 3-D glasses. Image processing and mosaic by Tim Parker, JPL. |
"Barnacle Bill" is a small rock immediately west-northwest of the Mars Pathfinder lander and was the first rock visited by the Sojourner Rovers alpha proton X-ray spectrometer (APXS) instrument. This pair of images shows super resolution techniques applied to the first APXS target rock, which was never imaged with the rovers forward cameras. Super resolution was applied to help to address questions about the texture of this rock and what it might tell us about its mode of origin. The first view of Barnacle Bill was produced by combining the "Insurance Pan" frames taken while the IMP camera was still in its stowed position on sol2. The composite color frame consists of 5 frames from the right eye, taken with different color filters that were enlarged by 500% and then co-added using Adobe Photoshop to produce, in effect, a super-resolution panchromatic frame that is sharper than an individual frame would be. This panchromatic frame was then colorized with the red, green, and blue filtered images from the same sequence. The color balance was adjusted to approximate the true color of Mars. The anaglyph view of Barnacle Bill was produced by combining the left (single red-filtered image) with the right eye frames by assigning the left eye view to the red color plane and the right eye view to the green and blue color planes (cyan), to produce a stereo anaglyph mosaic. This mosaic can be viewed in 3-D on your computer monitor or in color print form by wearing red-blue 3-D glasses. Image processing and mosaic by Tim Parker, JPL. |
