Finally we shall mention that it is also possible to supply an m-file containing your parameters as input to matpiv. The file parameters_example.m gives an example of how this may be achieved with the images in the Demo 1 directory. The user would then execute the following:
Here the file parameters_example.m is just a list of the parameters we would normally write on the command line:
% Parameter-example file im1= 'Demo1/im00.bmp'; %The "base" image im2= 'Demo1/im04.bmp'; %The "cross" image Dt=0.04; %Time between images winsize=[64 64;64 64;32 32;32 32]; %interrogation region size overlap=0.5; % Overlap of interrogation regions method='multin'; %Method for interrogation (i.e. multiple passes) wocofile='Demo1/worldco.mat'; %file containting the mapping from image to %world coordinates msk='Demo1/polymask.mat'; %file defining the regions to mask from the %flow.
