    <p>There is a lot of things that go on in red eye removal </p> <p>A. Eye Detection </p> <p>B. Red Eye Region Mapping</p> <p>C. Fill Color </p> <p>D. Fuzz</p> <p>E. Opaque </p> <p><strong>My advice</strong> </p> <p>If not a JOB for Jquery and even PHP would not remove red eye effectively </p> <p><strong>Likely Solution</strong> </p> <ol> <li><p>Get a Jquery area selection script where users can select their red eyes them self ( With this you would be able to get the region (X1 , Y1 , X2 , Y2 , Height , Width ) example <a href="http://odyniec.net/projects/imgareaselect/" rel="nofollow">http://odyniec.net/projects/imgareaselect/</a></p></li> <li><p>Have a simple Color Picker where they can select replacement color ??? Default can be black </p></li> <li><p>Send request to <code>imagemagick</code> using <code>exec</code> in PHP for the red eye removal </p></li> <li><p>You can not output your image ...</p></li> </ol> <p><strong>EDIT 1</strong></p> <p>I was able to help you get a ready command line tool for this JOB </p> <p><a href="http://www.fmwconcepts.com/imagemagick/index.php" rel="nofollow">http://www.fmwconcepts.com/imagemagick/index.php</a> http://www.fmwconcepts.com/imagemagick/redeye/index.php</p> <p>Basic Concept </p> <p>A. Create a desaturate copy of the input image</p> <p>B. Perform a fuzzy floodfill to create a mask image</p> <p>C. Composite the original with the desaturated image using the mask image</p> <p>D. Apply a morphologic close operation to fill in the specular hole in the mask and then create a difference operation to create a new mask of just the hole</p> <p>E. Apply the new mask to composite the previous result with a full lightness, zero saturation version of the original image</p> <p>Sample Process </p> <pre><code>convert -quiet -regard-warnings "$infile" +repage "$tmpA1" convert $tmpA1 -modulate $light,$sat,100 $tmpA2 proc="" for ((i=0; i&lt;np; i++)); do proc="$proc matte ${pairArray[i]} floodfill" done convert $tmpA5 -fuzz $fuzz% -fill none -draw "$proc" \ -fill "rgba(255,255,255,1)" +opaque "rgba(0,0,0,0)" \ -fill "rgba(0,0,0,1)" -opaque "rgba(0,0,0,0)" \ -alpha off -negate $tmpA3 if [ "$dilate" = 0 ]; then dilation="" else dilation="-morphology dilate disk:$dilate" fi convert $tmpA1 $tmpA2 $tmpA3 -compose over -composite $tmpA2 convert $tmpA3 \( +clone -morphology close disk:$rad $dilation \) \ -compose difference -composite -auto-level \ -negate -threshold 0 -negate $tmpA4 convert $tmpA2 \( $tmpA1 -modulate 100,0,100 \) $tmpA4 \ -compose over -composite $outfile </code></pre> <p>I hope this helps </p> <p>Thanks</p> <p>:)</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
