[[TracNav(Tutorial/TOC)]] = [wiki:Tutorial] / Processing image series = Open an image in UVMAT_DEMO03_PIVchallenge_2005C, representing a jet seeded by particles (accessible on http://servforge.legi.grenoble-inp.fr/pub/soft-uvmat/). The series contains 99 image pairs, labelled by a number with 3 digits and a letter index a and b. The nomenclature type '''[!NomType]''', given as the first image index, is therefore '001a'. Activate the menu bar option '''[Run/field series]''' to open the new GUI '''series'''. This GUI is used to launch various processing programs on field series. The program name is selected in the menu '''[!ActionName]'''. The default option 'check_data_files' just list the set of input files and checks their existence and type. The lower and upper indices for the input field series are given by '''first_i, last_i, and first_j, first_j''' for the second index a~1 and b~2, with an increment incr_i and incr_j for each index. The min and max indices in the series are given by the tables '''[!MinIndex_i], [!MaxIndex_i], [!MinIndex_j], [!MaxIndex_j]'''. As an example, set first_i=50, last_i=100, incr_i=10, first_j=1, last_j=2, incr_j=1. Pressing '''[RUN]''', the function 'check_data_files' is activated and yields the list of file names, with the two last ones, c100a.png and c100b.png, marked as not found. == Aver_stat, simple field average == This function provides field average or global statistics on the whole input file series. Let us set first_i=1,last_i=99, incr_i=1. Then run 'aver_stat'. The average image is displayed and stored as Images.stat/c001ab.png. == Aver_stat, global statistics == Other statistics can be obtained by aver_stat using a projection object. To create an object, go back to '''uvmat'''. Then check '''Projection object''' (tag = '''[!CheckObject]''') in series. == Time_series == This function provides the image intensity at a set of points versus time. First define the set of points as a projection object, using '''uvmat'''. Once you run the function, the GUI '''get_field''' appears (as well as the '''Figure1''') where you can select the coordinates of the figure. == Data organisation == Functions from series store results in files (except 'check_data_files'), so you need writing access on the data directory. An alternative possibility is to create a mirror directory using symbolic links so that the folders of the original images remains unperturbed. To create such a mirror, first open the images with the menu bar option '''[Open campaign/browse...]''' (instead of '''[Open/browse...]'''). Press the browser button '''[SELECT]''' when the camppaign .../UVMAT_DEMO_FILES appears in the upper window '''[titlebox]''' of the browser (then the list of subfolders appears in the main window '''[list]'''. This opens a new GUI '''browse_data'''. Each example folder is then considered as an 'Experiment', and their subfolders are '!DataSeries'. To create a mirror, press '''[create_mirror]''' and set the path to the mirror folder to be created. Then select an ''''Experiment' '''and a ''''!DataSeries' '''to open by '''uvmat'''. At the next opening you can directly open the mirror folder.
