| Description | This macro is dedicated to the wound healing analysis which measures the surface colonization by cells in a kinetic experiment. It measures the cell-free surface during time. After an illumination correction, the borders of the cellular mat are detected by an edge filtering followed by a gaussian filter. After an semi-manual intensity thresholding of the cell-free surface, it is measured with an exclusion threshold corresponding to 1% of the area measured in the previous image. A plot of the surface decrease is displayed as well as superimposing of the detected/measured area on the original stack. To try the macro with a dedicated use case : Stack_test_wound_healing

| Description | This macro is dedicated to the surface analysis of the adipocytes on tissue sections and coloration. It measures the surface and counts the number of cells in a field of view. After an RGB color separation, the borders of the cellular mat are detected by a FFT bandpass filter. The cytoplasmic surface is automaticaly thresholded with the Triangle method and converted to a binary mask. After a filling the holes in the mask, the surface is obtained for each cell.
