Eseguire ricerche approssimate in digiKam

Trascritto dal blog di Mohamed Malik, 17 marzo 2011

Uno degli strumenti più utili che puoi trovare in digiKam è la possibilità di eseguire ricerche approssimate in cui l'utente può supporre e disegnare i colori che potrebbero essere contenuti nell'immagine. Per poter eseguire una ricerca approssimata è necessario ricalcolare i codici di controllo delle immagini nel tuo database.

Per farlo vai su Strumenti -> Ricalcola tutti i codici di controllo e avrai due possibilità:

Scan

choose this option then digiKam will scan your database for missing fingerprint.

Rebuild All

choose this option then digiKam will rebuild all the fingerprints in your database.

After installing digiKam 2 beta 3 from source a few weeks back I created a new database for use with the developmental branch, in my Dual Core 3.2 GHZ ( FSB 800) & 2GB DDR3 RAM, rebuilding all fingerprints took around one and half hours. Therefore please remember that this operation of rebuilding all fingerprints can take sometime depending upon your system.

However the Scan option is quicker as it only searches for missing fingerprints. If you have already scanned your images for fingerprints then you should skip this step. On the left hand side of digiKam, look for the tool with wand and select that tool. Navigate to the tab Sketch. Choose a color that your image might contain, you can change the size of the pen which is on the scale of 1-10, and you can also choose the number of images that you want to be displayed during your fuzzy search, this can be set to a value between 1-50 items. As you sketch on the area you will see that the fuzzy search related images appears on the right hand side. After performing searches you might want to save the search results, in that case give it a name and press the Save button. See screen capture below.
