CICLOPS' Rev 49 Looking Ahead page is up. Highlights include a fourth monthy Voyager-class encounter with Tethys with 500m resolution over Odysseus (finally!)
Detailed mosaics of Rhea's prominent ray crater and points west are on tap for Old Scabby's second closeup. This should be a really cool periapsis passage to tide us over until the 10th of September. -------------------- ...if you don't like my melody, i'll sing it in a major key, i'll sing it very happily. heavens! everybody's all aboard? let's take it back to that minor chord...

Are any of the commercial photo packages (like Adobe) able to interpolate and fill in the truncated lines? eg by averaging the surrounding pixels?

It works pretty well to copy the area, paste it as a new layer, then nudge it one pixel up or down and select a filter that shows the max of the two layers' brightnesses. Basically, close the even numbered lines onto the odd ones. |

Basically, close the even numbered lines onto the odd ones. Which Photoshop filter does this? I've looked around and I can't find an obvious one. My trick for this has been to take a mask that I've made with alternating black and white lines, paste it onto the image, erase away the part of the mask that I don't need (covering the part of the image that is not affected by the truncated lines, then use the wand set to no antialiasing and non-contiguous pixels to select the lines from the mask that cover up the black pixels in the underlying image, then go to the underlying image, shift the selection by one pixel up or down to get to the good pixels, copy and paste. Using a filter that takes the maximum pixel value would be much much easier than this!! --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.
