Chapter 10: Visualization And Analysis
Regarding 16-bit and floating point (32-bit) images, various image filters and adjustment commands
are available (see "Available filters and adjustment commands" on page 749).
Image modes
If you are working with various image types and need to determine or convert images, choose Image
| Mode.
8 Bits/Channel: Indicates an 8-bit image. If working with 16-bit or 32-bit images, select
this option to convert to an 8-bit image.
16 Bits/Channel: Indicates a 16-bit image. Select this option to convert to a 16-bit image if
working with another image type.
FP-32 Bits/Channel: Indicates a floating point (32-bit) image. A floating point image
refers to any array of data that is visualized. Select this option to convert to a 32-bit image if
working with another image type.
You must convert an 8-bit or 16-bit image to grayscale to enable the FP-32 Bits/Channel
option.
The following table indicates the filters that can be used with each type:
Image type Available filters and adjustment commands
16-bit Average blur, Gaussian blur, Add Noise, Despeckle, Dust & Scratches,
Median, High Pass, Maximum, Minimum, Arithmetic, Binary Logic,
Expression, Image Math, Colorize, Invert, Levels, Curves,
Brightness/Contrast, Convolve, Hue/Saturation (RGB only), Color Balance
(RGB only)
FP (32-bit) Average blur, Median, Minimum, Maximum, Arithmetic, Expression, Image
Math, Convolve, Colorize
Binary filters
These commands can be applied to 8-bit grayscale images. For the Dilate, Erode, Open, and Close
commands, you must specify the number of iterations in a dialog box. Iterations refer to the number
of repetitions of a chosen filter.
