What we can do now is replace the edges you want with straight lines between the points like below.

So we have 19 vertex . we need total distance that  a hand edges have, and then we need to decide the distance that should  distribute equally in hand edges  ,.
but how ?  Please guide me

ahhan yes that's  good point , ok  lemme do that with program too . Is that ok  if i do or latter . or we can continue  with the image that you  made ?

Hi;

Hold on one second. You were asking for 10 points between each point. Wasn't that the original question?

Yes . . right . 

hmm ok but  i need to do equal distance between all edges  of my new image where vertex  are given .

The question i posted as a sample .that i have image like that just supposition,

But now i did some  editing in code and i got vertex  points . and i need to maintain equal distance between all  edges . .. Well question is same ,. just image  has changed

Note : the posted question was my thinking that  for example i need to maintain equal 10  distance between edges   .,

Hi model;

Soon you will understand everything you need!

Bear with me for a second. In your picture you have 19 red dots. If we super impose them on a piece of graph paper we can then read off the 19 pairs of x's and y's. So you see there are 19 points ( red dots ).

Once we have these xy pairs then the rest is algebra.

See the drawing below. You may have to blow it up a little in your browser. I have placed the points on graph paper. This is easily done using geogebra! Now we can read the xy coordinates of each one.

Do you follow me so far? If not where are you confused?

Well bob i understood your  finger .. .

yes Ok ..  the points that you drawn. i got those points on my original image of my hand.
So, now talk about  here about the equal distance between points . also note that my detected hand is waving continuously may be due to noise or lightning effect from environmental.  I meant detected  hand contours  and vertex  points are not stable so i  do't that in this case , how to handle equal distance between points

Hi;

I do not mind any jumping in.

Your question was always clear to me as long as we either get or have the xy coordinates.

I still require the coordinates of each red dot. Or a means to calculate them.

Hi ,

Can you  please use simple English . because your above sentence  are not  clear to me .

thanks

I thought you might since you suggested the distance formula.
You are going to add 9 in between points between each consecutive pair of points.
dX = X2 - X1
dY = Y2 - Y1
X coordinates of in between points = X1 + (dX/10); X1 + 2(dX/10); X1 + 3(dX/10)....
Same for Y coordinates.

Sir  can you  please explain the method graphically  too .

Thanks  alot ./

The drawing shows 19 red points. Your list has 15?

Well , that i supposed . also  vertex points can be change i meant increase or decrease depend on my hand postures .

so more postures , may be  create more edges . so  more vertex .  btw, in the above  image i just suppose that logically those should be my vertex .

well  i said edges points . and edge  made  by two  vertex . so .. i think i do't need to mention that  i have x and y of an edge .

In fact the image that i posted ,. i have hand contours that mean  edges  where edges made by two vertax , so that is clear,

Point here is i need to get equal distance between edges . for that i need to divide say all edges  should be divide into 10 equal distance part .

how can i divide into 10 distance equal parts ?

Hi TMorgan ,

I do't understand how to divide a straight line from  two points  into 10 equal distance . This same i have to do with all edges .

and then for dividing this distance into 10 parts  ,. how / ?

Are set operations exponential functions.  if so then how ?

Like logical or union . How  union is defined as exponential function ?

How set operations give result  in exponential form ?
