search images by color

[dlf1987]

Hi guys,

 

is there any way to make a search tool that finds images by their color using a color palette?

 

iv spent 4 hours searching google, and found nuthing php related...just coldfusion

 

Heres an example of what I'm looking for...

Having the color stored with the rest of the info for the picture would help you achieve this.  Just add another field into your database for color and allow a search by color.

yea, iv already thought of that, but the problem is that i have over 6000 images in my database 

 

for example this site is done in php... http://www.istockphoto.com/file_search.php and i know that they don't type in every individual color that matches the images in there image database.

Try something along the lines of this:

thanks Fearsoldier,

 

it worked good (with gif's), but the problem is that all my product images are jpg, and imagecolorexact doesn't work with jpg's, is there a way to make it work?

 

is there a way to convert the jpg to a gif, to be used with imagecolorexact ?

i got the convert from jpeg to gif work, but it loses alot of the color... any one know what im missing? if i am...

 

$sourcePath = '../images/product-images/'.$row_rsCat['CatImage'].'/'; // Path of original image
$sourceUrl = '../images/';
$sourceName = $row_Recordset1['ProItemNumber'].'-100.jpg'; // Name of original image
$thumbPath = '../images/thumbs'; // Writeable thumb path
$thumbUrl = $sourceUrl . '/';
$thumbName = $row_Recordset1['ProItemNumber'].'-100.gif'; // Tip: Name dynamically
$thumbWidth = 100; // Intended dimension of thumb

// Beyond this point is simply code.
$sourceImage = imagecreatefromjpeg("$sourcePath/$sourceName");
$sourceWidth = imagesx($sourceImage);
$sourceHeight = imagesy($sourceImage);

$targetImage = imagecreate($thumbWidth,$thumbWidth);
imagecopyresized($targetImage,$sourceImage,0,0,0,0,$thumbWidth,
$thumbWidth,imagesx($sourceImage),imagesy($sourceImage));
imagegif($targetImage, "$thumbPath/$thumbName");

// By now, the thumbnail is copied into the $thumbpath
// as the file name specified in $thumbName, so display
echo '<img src="'.$thumbUrl.'thumbs/'.$thumbName.'" />';

 

thanks
