i would like to get the amount of cells that have changed since last frame .

they can only be 0 or 255 , they never are 110 , or 32 , ...

jit.change doesn't seem to be able to give this information , efficiently (scanning threshold settings is not a good way ) .

best would be a jit.gen solution , and i'm still stuck ,as i'm trying to find my way in this programming style ...

i'm working at low resolutions (100x200 , 10x40 , .... , that kind)

hi ,
i'm working on 1 char matrices .

how-to-report-the-amount-of-different-cells-from-consecutive-frames

unfortunately , i'm looking for another counting method .

here is a small modification on your patch .

i have just replaced the jit.noise with 2 matrices which have 4 different cells .

i'm looking for a way to compare each cell one by one ,

in this case ,it would report that 4 cells have changed .

i was hoping to find something in CV.jits ,

hi LSKA ,
thanks a lot for your answer ,

but i still haven't .


it's working 100% in all the cases i've tried .

i would definitely need to practise on the different ops of jit op ,

it's not the first time i can read your good advices , christopher ,

it's already been the case on some other threads ,

thanks again , for this , and the other times .

also , thank you lska , your patch made me want to understand it better .

hi Christopher ,

it is so often the key to my needs !
