Input data with image of the cell population

Input should be a matlab-readable image, the input can be a matlab matrix or the name of the file. For instance if the file "Example.tif" is in the matlab path, it can be read into matlab:

dataIn=imread('Example.tif');
imagesc(dataIn);
colormap(gray)

Or it can be passed as a string

dataIn='Example.tif';

Process the data with cellMigration

dataIn, either as a string or a matrix, is the only input parameter required for the algorithm of measurement of cell migration:

[Res_stats,Res_colour,Res_gray]=cellMigration(dataIn);

Output of the algorithm

The output arguments are the following: Res_stats, which will contain the minimum, average and maximum distances:

disp(Res_stats)

    minimumDist: 268.0765
        maxDist: 416.9149
         avDist: 324.3023
           area: [2x1 double]

The area covered by the wound is stored as number of pixels and as a relative to the total area of the image:

disp(Res_stats.area(1))
disp(Res_stats.area(2))

      585570

0.1911

The output images will display the original image with the boundaries overlaid:

imagesc(Res_colour);
