The threshold value represents a threshold amplitude which corresponds to the lowest available colour value All amplitudes below this value obtain this colour Thus it can be used to remove a noisy background from the visualisation It has to be applied carefully as it may also remove true reflection energy 2 9 6 Negative Flank Suppression Negative flanks occur wherever a pixel will obtain a colour which is less than the colour of the pixel above In that case the pixel is set to the lowest colour This algorithm enhances the optical vertical resolution on the screen as distinct reflectors are more clearly separated from each other Doc Id ED 6006 G 212 Filename ATLAS ParaStore 3 V11 UM V15 doc Edition 06 2004 Version 1 5 Status Final 2 11 ATLAS PARASTORE 3 Version 1 0 2 System Overview USER MANUAL 2 9 7 Logarithmic Scale With logarithmic scale enabled the color scale is adjusted logarithmically Thus more colours are available for lower signal amplitudes and less colours are available for higher ones This option can be valuable to distinguish weaker reflectors However true amplitudes are much harder to estimate 2 10 Colour palettes Predefined colour palettes are used for the colour coded visualisation of data These palettes may e adjusted to fit specific needs or preferences The palettes are plain ASCII files with the following record format red green blue comment Each record defines one colour The pal

To increase the signal to noise ratio S N and to enhance the image quality of the data visualisation several numerical and graphical processing algorithms can be applied 2 9 1 Subtract Mean The mean amplitude value of the visible depth window is calculated and subtracted from each samples amplitude to remove constant offsets in the data 2 9 2 Band Pass Filter This is a very fast filter algorithm operating in the time domain Lower and upper boundaries of the filter may be varied appropriately to the signal frequency Filter flank steepness can be influenced by applying the filter several times Filter Iteration This filter should be applied to reduce noise 2 9 3 Adaptive Band Pass Filter This filter uses the same algorithm as the band pass filter But here the width of the pass band is selected and the filter automatically centres itself on the main signal frequency This becomes quite handy if the signal frequency is varied for specific purposes as for example penetration or resolution studies 2 9 4 Clip The clip value represents a threshold amplitude which corresponds to the highest available colour value All amplitudes above this value obtain this colour Thus it can be used to emphasize weaker reflectors in the echogram and should be adapted carefully on the sedimentary environment If clipping is switched off the echograms will be scaled to the maximum amplitude in the depth window on a per trace basis 2 9 5 Threshold
