1 Color Palette using LUT Parametric Bitmap (Integer, Float or - PowerPoint PPT Presentation

1 Color Palette using LUT Parametric Bitmap (Integer, Float or Double) Maximum Value Minimum Value (0028,xxx4) (0028,xxx5) e.g. 0 % e.g. 100 % LUT Would need: • Number of LUT entries (if table is used) • Minimum Value (First value mapped) • Maximum Value (Last value mapped) • Number of Bits

Segmented Palette Color Lookup Table • Example: R-Descriptor G- Descriptor B-Descriptor Segments Seg0 0,205,255 0,1,255 0,1,127 300 Seg1 1,51,105 1,127,0 1,127,0 Seg2 0,128,0 0,128,0 250 200 • Describes: 150 operator range R G B 100 constant 0 255 204 255 50 ramp 205 255 255 105 0 ramp 0 255 0 50 100 150 200 250 300 127 0 R G B ramp 0 127 127 0

Segmented Palette Color Lookup Table • Example: • With • First segment type R-Descriptor G- Descriptor B-Descriptor Seg0 0,205,255 0,1,255 0,1,127 • 0 is discreet Seg1 1,51,105 1,127,0 1,127,0 Seg2 0,128,0 0,128,0 • 1 is linear • 2 is indirect • Second is length • Describes: • Third is Value operator range R G B • Discreet assume error constant 0 255 204 255 • Linear it is end value ramp 205 255 255 105 ramp 0 255 127 0 ramp 0 127 127 0

1 Color Palette using LUT, Threshold defines visible segments Parametric Bitmap (Integer, Float or Double) Maximum Value Minimum Value (0028,xxx4) (0028,xxx5) e.g. 0 % e.g. 100 % Visible after applying Threshold LUT Threshold Threshold Threshold Threshold Note : Min1 Max1 Max2 Min2 Threshold is not part of parametric map but for presenting area’s of interest
