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

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?

wait wait . . I got those points by running my program ..

but the above posted figure for question is good for understanding that i want,.

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;

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 .,

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

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 ?

bobbym · 2011-10-31 12:36:09

You want to work on it yourself now?

no no no .. I was just thinking to draw the same edges on my hand ,. but i think latter,. please complete this from the image that you posted. please continue .

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

Hi;

The way to solve any problem is to stop thinking of it as a whole. They are usually too hard and too big to hold in ones mind. Be like a computer, one little step at a time and soon the whole job is done.

One point at a time. What would you like done between A and B in the diagram?

hmm well , again equal distance .. between A and B.

hmm well , again equal distance .. between A and B. and this distance should be same between B and C . and so on . .

bobbym · 2011-10-31 12:53:24

You want to put how many points between A and B. All equally spaced?

hmm . well i am getting you step by step point . .:)
because i think we need to find the distance between all edges and then we can decide what should be the distance that would be equal in between edges .
Ok please continue. I must finish it ,

yes right

bobbym · 2011-10-31 12:57:13

Yes, do you want to place 10 equally spaced points between A and B? Do not even think about B to C yet. We are only on the first step.

hmm ok from 5 points for equally spaced .

hmm ok sorry , well for5 points equally spaced

bobbym · 2011-10-31 13:00:23

I have to be sure here! 5 points between A and B all equally spaced?

bobbym · 2011-10-31 13:02:13

Okay. I will need time to work on it now. I will post the solution and a method as soon as I get it.
