Operation ACE Reference Guide, 18317-000 Rev A Page 400 Value Name Description 22 hsFilteringVerticalPrewitt Applies a Vertical Prewitt filter. 23 hsFilteringGaussian Applies Gaussian filter. 24 hsFilteringHighPass Applies High Pass filter. 25 hsFilteringMedian Applies a Median filter. 26 hsMorphologicalDilate Sets each pixel in the output image as the largest luminance value of all the input image pixels in the neighborhood defined by the selected kernel size. 27 hsMorphologicalErode Sets each pixel in the output image as the smallest luminance value of all the input image pixels in the neighborhood defined by the selected kernel size.
28 hsMorphologicalClose Has the effect of removing small dark particles and holes within objects. 29 hsMorphologicalOpen Has the effect of removing peaks from an image, leaving only the image background. 30 hsHistogramEqualization Equalization operation enhances the Input Image by flattening the histogram of the Input Image 31 hsHistogramStretching Stretches (increases) the contrast in an image by applying a simple, piecewise, linear-intensity transformation based on the histogram of the Input Image. 32 hsHistogramLightThreshold Changes each pixel value depending on whether they are less or greater than the specified threshold.
If an input pixel value is less than the threshold, the corresponding output pixel is set to the minimum acceptable value. Otherwise, it is set to the maximum presentable value. 33 hsHistogramDarkThreshold Changes each pixel value depending on whether they are less or greater than the specified threshold. If an input pixel value is less than the threshold, the corresponding output pixel is set to the maximum-presentable value. Otherwise, it is set to the minimum-acceptable value. 34 hsTransformFFT Converts and outputs a frequency description of the input image by applying a Fast Fourier Transform (FFT).
35 hsTransformDCT Converts and outputs a frequency description of the input image by applying a Discrete Cosine Transform (DCT).Parameters
