Computer Processing Brings out Eros's Details Target Name:   Asteroid Eros Spacecraft:   NEAR Produced by:   NASA/JHU-APL Copyright:  NASA Copyright Free Policy Date Taken:   12 February 2000 Date Released:  16 February 2000 Related Document Asteroid 433 Eros Download Options Name Type Width x Height Size eros15.jpg JPEG 640 x 480 45K eros15.jpg JPEG 1500 x 1125 119K eros15.tif TIFF 1500 x 1125 635K The NEAR camera's ability to show details of Eros's surface is limited by the spacecraft's distance from the asteroid. That is, the closer the spacecraft is to the surface, the more that details are visible. However mission scientists regularly use computer processing to squeeze an extra measure of information from returned data. In a technique known as "superresolution", many images of the same scene acquired at very, very slightly different camera pointing are carefully overlain and processed to bright out details even smaller than would normally be visible. In this rendition constructed out of 20 image frames acquired Feb. 12, 2000, the images have first been enhanced ("high-pass filtered") to accentuate small-scale details. Superresolution was then used to bring out features below the normal ability of the camera to resolve. (Mosaic of images 0125957025 and 0125957087)
