coordinate representation about clmtrackr HOT 6 CLOSED

Hi, glad you like the library! The coordinates should be relative to the upper left on the html video as you expected, i.e. coordinates (0,0) should be top left on the video (unless of course I've done something wrong). Exactly how wrong is the x-value?

from clmtrackr.

well i put my face on the upper left html video and the point 19 gave me the following values:

x: 238.15687982454853, y : 21.141415153990234,

always give me a range between value 200 and 300 in the x coordinate

I did a test now, and getCurrentPosition() seems to work as expected here, i.e. x-values are correct. Do you have any example code to reproduce wrong x-values?

from clmtrackr.

based in your example code,

in the drawLoop method i do this:

var facialPoints = ctrack.getCurrentPosition(); //get the facial array
var arrFacePoints = []; //for save face points in json array
for(int i=0, i<=70;i++) { //number of points in your face representation
var strAux = facialPoints[i]; //get the current couple of coordinates
var coorX = strAux[0]; //get x
var coorY = strAux[1]; //get y
arrFacePoints.push({punto: i, coorX: coorX, coorY: coorY}); //save in json array
}
console.log(arrFacePoints); //print result

and then i want to asking about which one is the maximun range of values for your coordinate representation for the x and y axis?

by the way, sorry for the late respond.

regards...

Hi,

well I was a bit late responding as well. I tried your code, and it works as expected (though there were some small errors), the coordinates are correct. I think the reason for what you are seeing is that in the examples I've put online, I flip the video horizontally with CSS, so that the movements in the video match your movements, i.e. when you move your head to the right, the head in video moves right, etc. This was just to make it more natural, since I always got confused by the actual unflipped video. Since the source of the video is not flipped, just the styling, the x-coordinates you receive refers to the unflipped video. So when you move your head to top left, in the (unflipped) video you are actually in top right, therefore the x-coordinate will not be close to 0, but close to the width of the video source, which in this case I guess it means it is close to 300.

Let me know if this is the case for you.

Hi,

Don't worry man it's fine. I checked what you saying me and everything it's wonderfull. I thought the origin was in the other side in my hand left (me in front of the computer) and now i know is in the right side of the canvas, thanks for all.
