3D Filtering Functions
DOLPS3D Returns a DICOM image, each value of which is calculated as the difference between the input image low pass filtered 6 times and the input image lowpass filtered 3 times. Each low pass filtering is carried out with a 3x3x3 kernel.
LIN3D Returns a DICOM image, each value of which is calculated as the largest intensity value in a 3x3x3 three-dimensional region of the input image low pass filtered with the kernel centred at the location in question.
LowPass3D Returns a DICOM image, each value of which is calculated as the mean intensity value in a 3x3x3 three-dimensional region of the input image
Midpoint3D Returns a DICOM image, each value of which is calculated as the midpoint between the highest and lowest intensity values in a 3x3x3 three-dimensional region of the input image
Sharpen3D Returns a DICOM image, each value of which is calculated as the difference between a weighted input image and the input image low pass filtered with the a 3x3x3 three-dimensional kernel centred at the location in question
SIN3D Returns a DICOM image, each value of which is calculated as the smallest intensity value in a 3x3x3 three-dimensional region of the input image with the kernel centred at the location in question
FreiChen3D Returns a DICOM image, each value of which is the edge magnitude value calculated using a three-dimensional FreiChen kernel calculated in a 3x3x3 region of the input image
Laplace3D Returns a DICOM image, each value of which is the edge magnitude value calculated using a three-dimensional Laplace kernel calculated in a 3x3x3 region of the input image
NonMax3D Returns a DICOM image, each value of which is the edge magnitude value calculated using a three-dimensional NonMaxima kernel calculated in a 3x3x3 region of the input image
Prewitt3D Returns a DICOM image, each value of which is the edge magnitude value calculated using a three-dimensional Prewitt kernel calculated in a 3x3x3 region of the input image
Roberts3D Returns a DICOM image, each value of which is the edge magnitude value calculated using a three-dimensional Roberts kernel calculated in a 2x2x2 region of the input image
Sobel3D Returns a DICOM image, each value of which is the edge magnitude value calculated using a three-dimensional Sobel kernel calculated in a 3x3x3 region of the input image
Gauss3D Returns a DICOM image, each value of which is the magnitude value calculated using a three-dimensional Gauss filtering kernel calculated in a 3x3x3 region of the input image
Median3D Returns a DICOM image, each value of which is calculated as the median intensity value in a 3x3x3 three-dimensional region of the input image centred at the location in question
Mask3D Returns a DICOM image, each value of which is the same as the input image, except for the region around the edges in the x, y, and z dimensions where a black border of width border is drawn
