 How can you find the "majority colors" of an image using PHP?

hope this fix your issue Here's one approach: 1) Define a set of colours which we'll call centroids -- these are the middle of the basic colours you want to break images into. You can do this using a clustering algorithm like k-means, for example. So now you've got, say, 100 centroids (buckets, you can think of them as), each of which is an RGB colour triple with a name you can manually attach to it.

 Color histogram bins by majority class

around this issue Just take a look at the code of hist.default, how this is handled there... code :
color_hist <- function(x, cats, xlab = xname, main = paste("Histogram of", xname), ...){
xname <- paste(deparse(substitute(x), 500), collapse = "\n")
hist <- hist(x, plot=FALSE, ...)
cuts <- cut(x, breaks=hist$breaks)
color = apply(table(cuts, cats), 1, which.max)
hist(x, col=color, xlab = xlab, main = main, ...)
}
color_hist(iris[,4], iris[,5])

 click function should invert color of an image and restore the color of previously inverted image
By : Pankaj Kumar
Date : March 29 2020, 07:55 AM
help you fix your problem You need to add a line in your click function that removes the .pressed class from the element that you'd clicked previously code :
.click(function() {
var imgid=$(this).data('imgid');
$('#demo').text("click for "+imgid);
$('.pressed').removeClass('pressed');
$('#'+imgid)
.toggleClass('pressed')
.css('z-index',2);
});

Is it possible to get the majority color of an emoji?

Hope that helps An alternative approach without using text-shadow is to copy the emoji, place it directly behind the original and blur it. You could create the copy directly in the HTML, or if easier use js, as in the example below. code :
var emoji = document.querySelector("#blur-me");
var copy = emoji.cloneNode(true);
copy.classList.remove("emoji");
emoji.appendChild(copy);
.emoji {
padding: 3px 6px;
font-size: 24px;
position: relative;
display: inline-block;
}
.emoji span {
position: absolute;
left: 6px;
z-index: -1;
filter: blur(10px);
}
<span class="emoji" id="blur-me"></span>
