Opticks is the spelling used by Sir Isaac Newton in his treatise on light and optical systems

20. Adopted due to it's historical interest, contextual relevance, and uniqueness. 21. Histogram

View histogram and current stretch at the same time

Quickbird image shown 22. Histogram

Stretch has been compressed, increasing contrast

47. Can manually be executed as one-click or can be automated Bin bands together for current dataset and then run principal component analysis 48. Opticks Batch

Run wizards without a gui or user intervention

49. External tool can modify .batchwiz xml file to adjust input arguments Load image, execute band math expression, export results to new file 50. Spectral Processing Extension

Adds hyper-spectral and multi-spectral image analysis tools

51. Signature plotting window 52. Signature library tools 53. Signature matching algorithms 54. Hyper-spectral anomaly detection tools 55. Atmospheric normalization 56. Spectral Signature Plotting

View signatures without imagery, drag and drop onto plot to view

Aster Spectral Library signatures shown 57. Spectral Signature Plotting

View in-scene pixel and AOI spectra

AVIRIS image and in-scene signatures shown 58. Minimum Noise Fraction Transform

Segregate noise and improve later processing

AVIRIS image shown 59. RX (Reed-Xiaoli) Detector

Detects pixel spectra that differ from the background

SAMSON image shown with detected anomalies in red 60. TAD (Topological Anomaly Detector)

Detects pixel spectra that differ from the background using non-uniform segregation

SAMSON image shown with detected anomalies in red 61. SAM (Spectral Angle Mapper)

Match known signature to pixels in an image

SAMSON image shown with matched pixels in red 62. CEM (Constrained Energy Minimization)

Match known signature to pixels in an image

SAMSON image shown with matched pixels in red 63. ACE (Adaptive Cosine Estimator)

Match known signature to pixels in an image

SAMSON image shown with matched pixels in red 64. Spectral Library Match

Load 100s or 1000s of signatures

65. Click a pixel and determine the best matches from a pre-loaded library SAMSON image shown with ASTER spectral library signature matches 66. NDVI

Automatically calculate the NDVI of a multi-spectral or hyper-spectral image

NDVI (Normalized Difference Vegetation Index) results for SAMSON image shown 67. Spatial Profile Plotting

Plots horizontal and vertical slice based upon pixel that was clicked

68. Creates line for each of the displayed bands AVIRIS image shown 69. Opticks Scripting Support

A scripting extension(s) must be installed (currently Python, IDL)

70. Scripting Window to interactively enter commands and manipulate Opticks 71. Script code can be added to wizard in Wizard Builder

Can then be added to menu and executed with one-click

Scripts can be bundled into installable extensions 72. Python Scripting Extension

Requires Python install (2.5 or 2.6)

73. Numpy is recommended by not required 74. Python can manipulate:

Windows/Layers

75. Images 76. AOIs, Signatures, Animations, Wizards 77. Any other plug-in (e.g scripted Wizard Builder) 78. Interactive Python Scripting

Script Opticks as you work
