NAME ^

Image::DominantColors - Find dominant colors in an image with k-means clustering.

VERSION ^

Version 0.01

SYNOPSIS ^

This module does just one simple thing. It scans an image and clusters colors with the k-means clustering algorithm to give you the most dominant colors in that image.

Here is a live demo : http://www.tryperl.com/dominantcolors/

This is how it works, I would advise leaving the clusters to a default 3 which works best with images.:

    use Image::DominantColors;
    use Data::Dumper;
    
    
    my $dmt = Image::DominantColors->new({file => 'some_path/img.jpg', clusters => 4});
    #OR three clusters is default
    my $dmt = Image::DominantColors->new({file => 'some_path/img.jpg'});
    my $r = $dmt->getDominantColors();
    
    print Dumper($r);
        #This outputs the following:
    # [
    #           {
    #             'r' => 31,
    #             'b' => 23,
    #             'g' => 15
    #           },
    #           {
    #             'r' => 193,
    #             'b' => 41,
    #             'g' => 84
    #           },
    #           {
    #             'r' => 114,
    #             'b' => 136,
    #             'g' => 128
    #           },
    #           {
    #             'r' => 61,
    #             'b' => 82,
    #             'g' => 66
    #           }
    # ];
    ...
