a map of "lighted" pixels in a sequence of images

parfait evouna
hi there. I would like to have a Map as the Sam's HeatMap from stack Plugin does.
 
I have the "how to do" in natural language but i'm a beginer in programming macros with imageJ.
 

I have a stack of images with a certain number of rows and columns (RxC)
have access to the number of pixels and save it as N.
create a new frame RxC dimensions.
After the use of Threshold command or Analyze Particles on the stack of images, i would like to walk on each pixel of each image to look for which one has the 255 value and count the number of times this pixel at this position has this value (255) across the stack.
This number of times, i would like to store it in the new frame at the position of the concerning pixel.
Finally, i would like to color the pixels of the created frame after the storage step according to the pixel values.
 
Best regards,
Parfait
