satofilter¶
Syntax: satofilter(input image, output image, spatial sigma, scale, gamma, gamma23, gamma12, alpha)
Calculates line-enhancing filter lambda123 according to Sato - Three-dimensional multi-scale line filter for segmentation and visualization of curvilinear structures in medical images.
This command can be used in the distributed processing mode. Use distribute command to change processing mode from local to distributed.
Arguments¶
input image [input]¶
Data type: uint8 image, uint16 image, uint32 image, uint64 image, int8 image, int16 image, int32 image, int64 image, float32 image
Input image.
output image [output]¶
Data type: uint8 image, uint16 image, uint32 image, uint64 image, int8 image, int16 image, int32 image, int64 image, float32 image
Output image.
spatial sigma [input]¶
Data type: real
Standard deviation of Gaussian kernel, determines scale of structures that are probed.
scale [input]¶
Data type: real
Default value: 0
Output values are scaled by this number. Pass in zero to scale output value 1 to maximum of the data type for integer data types and to 1 for floating point data types.
gamma [input]¶
Data type: real
Default value: 0
Scale-space scaling exponent. Set to zero to disable scaling.
gamma23 [input]¶
Data type: real
Default value: 1
\(\gamma_{23}\) parameter; controls the sharpness of the selectivity for the cross-section isotropy. Only non-negative values are valid.
gamma12 [input]¶
Data type: real
Default value: 1
\(\gamma_{12}\) parameter. Non-negative values are valid.
