HPF Design Dialog Box (Image Tool)
Generate a highpass filter.
Butterworth—If selected, a Butterworth filter is generated.
Ideal—If selected, an ideal filter is generated.
Cutoff—Enter scalar floating-point value for the cutoff frequency of the filter.
Save Filter As—Enter a name for the filter.
Filter Order—A scalar floating-point value for the filter order. This option is active only when Butterworth is selected.
Maximum—Enter a scalar floating-point value to specify the maximum value of the filter. (Default: DC_Offset + 1.0)
DC Offset—Enter a scalar floating-point value to specify DC offset of the filter. (Default: 0)
Cutoff Amplitude—Enter scalar floating-point value for the cutoff amplitude of the filter. This option is active only when Butterworth is selected.
Width—The x-dimension of the filter.
Height—The y-dimension of the filter.
DC at Center—If set, shifts the output so that the center of the filter is the same as the center of the array.
OK—Generate the filter and exit the dialog box.
Apply—Generate the filter, but do not exit the dialog box.
Cancel—Dismiss the dialog box without taking any action.
Help—Display online Help on the dialog box.
