INTRODUCTION TO LASER SCANNING MICROSCOPY
LSM 510 Functions
B 40-051 e 07/98 5-33
Smooth (Gauss)
This function performs a Gauss filter.
Fig. 5-16
The noise in the image sequence is reduced, the edge shape is nearly unchanged, local maxima are
leveled, the dynamic range is reduced.
Image sequences should be smoothed before they are reconstructed or segmented. For most sequences
a Size value of 3 is sufficient enough. If Input is a multichannel sequence, any number and combination
of channels can be selected. Output will only get the selected channels as results.
The grey value of every pixel is substituted by a weighted average of its surrounding neighbors. The
neighbors are defined by a cube. The affected pixel is the central pixel of the filter cube. The weighted
filter cube is approximated by a binomial distribution. The size of the filter cube is set using the Size
scroll bar. Even numbers are set to the next odd value. The Size defines the strength of the smoothing.
Parameters:
Input Input image sequence
Output Output image sequence
Size Filter size (3...31, only odd numbers)
