The Data Big Bang and the Expanding Digital Universe: High-Dimensional, Complex and Massive Data Sets in an Inflationary Epoch
Figure 3
Overlaid pre- and postprocessed images [28]. (a) Three overlaid images of IC 405: Spitzer IRAC camera 8.0 m image, the module of its gradient, and the angle of its gradient (red, green, and blue, resp.). The line through the red cross “x” indicates the crosscut. (b) Three profiles for the crosscut through ‘‘x’’. The crosshair goes through the ridge point and a local minimum of the module of the gradient. Note the different scales on the left and right vertical axes.
