v44 v45 52 52 It can be useful to visually superpose the images to the velocity field. This is done by selecting the option 'vec(U,V)' in the popup menu '''[!FieldName] '''and 'image' in the popup menu '''[!FieldName_1]''', located just below''' ''' in the upper frame '''[Input]'''. To remove the image, select the blank option in '''[!FieldName_1]'''. 53 53 54 54 [[Image(Tutorial5 - Image+Vectors.png)]] 55 55 56 56 Similarly, the velocity vectors can be superposed to the vorticity field, selecting 'vort'''' ''' in '''[!FieldName_1]''' instead of 'image'''''''.''' … … 92 92 The mask image can be seen as a mask by selecting '''[view_mask]''' at the upper left of the GUI '''uvmat'''. For checking purpose, it can be also opened by the browser of '''uvmat''' like any image. In the GUI '''civ_input''', the mask is introduced by the selecting the green check box '''[Mask]'''. Vectors under the mask are not calculated in the resulting velocity data. 93 93 94 94 [[Image(Tutorial5 - CIV with mask.png)]] 95 95 96 96 Further improvments of the results are discussed in Tutorial/CorrelationImageVelocimetryOptimisation
