image processing - How to calculate/represent rate of change of a pixel in ImageJ -


the following in reference dynamic 16-bit images in imagej64.
aiming able "plot" rate of change each pixel in image whole sequence of images (60 per set) , use different gradient values of plot representation of change in pixel on time displaying dynamic data still image. ideas on start , tools may of use?

there many possible "rates of change", depends on particular application. of possible solutions include (assuming pix set of particular pixel's values across images):

  • values amplitude max(pix)-min(pix)
  • values variance (or standard deviation) var(pix) (or std(pix))

more complex functions can used, if interested in actual "visual effect change" rather simple pixel value example computing variance of directional partial derivatives etc. stated before - depends on application, kind of change interested in.
