Hello guys,
any update?
Regards,
Look at the examples below.
// Default colors //===================
tracking.ColorTracker.registerColor('cyan', function(r, g, b) {
var thresholdGreen = 50,
thresholdBlue = 70,
dx = r - 0,
dy = g - 255,
dz = b - 255;
if ((g - r) >= thresholdGreen && (b - r) >= thresholdBlue) {
return true;
}
return dx * dx + dy * dy + dz * dz < 6400;
});
tracking.ColorTracker.registerColor('magenta', function(r, g, b) {
var threshold = 50,
dx = r - 255,
dy = g - 0,
dz = b - 255;
if ((r - g) >= threshold && (b - g) >= threshold) {
return true;
}
return dx * dx + dy * dy + dz * dz < 19600;
});
tracking.ColorTracker.registerColor('yellow', function(r, g, b) {
var threshold = 50,
dx = r - 255,
dy = g - 255,
dz = b - 0;
if ((r - b) >= threshold && (g - b) >= threshold) {
return true;
}
return dx * dx + dy * dy + dz * dz < 10000;
});
your question is already answered.
Hello support,
I am trying to track the r,g,b colors instead of cyan, magenta and yellow, so in the registerColor function i have changed the values (or add a new registerColor function): tracking.ColorTracker.registerColor("red", function (t, r, n) { var e = 50, a = t - 255, i = r - 0, o = n - 0; return t - n >= e && r - n >= e || a a + i i + o * o < 1e4
But how can i knot the correct values that i have to put in the formula for e,a,i,o ? i tried many values instead of 255 and 0 and still not working. so how can i track the red, green, and blue colors?
Regards,
