Photo face recognition
Faces feature works like this: by analyzing the unique properties of each face in each photo—the distance between the eyes, nose, mouth, hair color, lack of hair, and so on— Phototheca attempts to detect and recognize the people in the photos of your library and group them into stacks. When the setup process is complete, you’ll see these stacks when you click the Faces icon in your Source list.
Phototheca makes the first pass at this automatically. After the initial pass, Phototheca requires you to review stacks with photos and confirm it’s subject’s identity. (It’s easy and fun!) After that, you can click the Faces icon in the Library list to see that Phototheca has grouped your pictures by the people in them.
Faces view is accessible from the left panel:
Phototheca displays a corkboard with Polaroid-style shots of each person and pet you’ve tagged so far, labeled with names you assigned.
Use Zoom slider in the Phototheca toolbar to change a thumbnail size and, thus, the number of shots in a row. To see all the photos of each person, double-click a face. To go back to the Faces corkboard, click “All Faces” at the top left of the photo-viewing area.
Automatically Faces Recognition
When you upgrade from an earlier version, Phototheca automatically starts to detect faces. The first time you run Phototheca, the program upgrades a photo library —and gets to work searching all your images for human faces or cats.
Phototheca displays the progress of faces recognition on the panel above the corkboard. You can pause the recognition process and resume it with corresponding buttons on the panel.
Note: The recognition process depends on the number of photos you’re importing, and it may take quite some time to complete its initial faces detection.
This part of the setup doesn’t require any manual actions from you, and it happens each time new photos are being imported to the library.
After completing its scan, Phototheca has a first impression of your friends and family.
But it still does not know who they are, and what those people’s names are.
Note: If Phototheca doesn’t detect any faces in your photos, you see an empty corkboard.
Tagging Faces Automatically
Now that Phototheca has done its face-detection run, it’s time to tag your friends and family. Once you label a face, the app looks around and tries to match it up with other similar faces in the library, using AI technology. The whole face-tagging process is incredibly simple:
- Click Faces in your Source list.
- Click Find Faces on the toolbar
Phototheca displays thumbnails of a few unknown faces it found in the library.
2. To tag a face – click the “unnamed” label below a thumbnail and type the person’s name, and then hit Enter.
You can type any name you want—like Mom or Uncle Robin—but it’s a good idea to stick with the person’s real name.
Note: Don’t waste time to naming blurry or poorly lit photos, or those with microscopic faces. Each time you name a photo, Phototheca broadens its range of suggested photos for that person. Naming bad shots makes it harder for Phototheca to recognize people.
When you’ve completed the naming exercise, click Continue to Faces at the bottom right of the Phototheca window. You now see a corkboard with Polaroid-style shots of each person you’ve tagged so far, labeled with the names you just assigned.
Tagging Faces Manually
If Phototheca fails to detect a face during import — it happens not very often—you can always tag it yourself. Start by selecting the photo and then open the Info panel. In the Info panel, click the “Add a face” label.
A white square appears, which you can drag over onto that undetected face. Drag the corners of the square to resize it.
When you’ve placed the white square right where a face is, click the “click to name” button and type the real name of the person.
Adding More Photos to a Name
Once you’ve set at least one name to a face, Phototheca’s powers of recognition really start to work. Basically, this AI-driven feature can recognize faces with high accuracy, but sometimes it’s just not sure enough if photos belong to the same person or not. You can help it to match up the names and faces it’s not sure about:
1. Double-click a person on the Faces corkboard. Phototheca shows all the photos you tagged already with this person’s name. At the bottom of the dialog, you see a note telling you how many other pictures Phototheca thinks to contain this same person.
2. Just above the Phototheca toolbar, click Confirm Additional Faces button.
The app now shows a screen full of tiles. Each tile contains a close-up of the lucky person’s face, and each taken from a different file. The caption “click to confirm” appears beneath each photo. This is your chance to tell Phototheca’s face-detection software how it did.
Click a photo once to confirm that Phototheca has correctly matched this face with the name. When you click a photo, the “click to confirm” bar turns green and displays the name of the person—for example, Tia. Behind the scenes, Phototheca learns from your selection. “Ah, OK—that’s Tia,” it says to itself. This helps Phototheca to refine its recognition smarts for next time.
When you see a tile that shows somebody else— Phototheca has picked the wrong person—Ctrl-click it. The “click to confirm” caption turns red, and the text says, “Not Tia” (or whoever).
When you’re completed accepting or rejecting tiles, click Done. The more guidance you give Phototheca in identifying people in your photos, the more accurate it becomes at recognizing them in new photos.
Search for a Face
Moving on with your confirmation of faces, you refine the Faces feature.
Eventually, you finish with a whole array of headshots on the Faces corkboard. The next time you need to see pictures of Chloe, double-click her Polaroid on your Faces corkboard; Phototheca displays close-ups of all the photos she’s in.
Type a face name in the search box on the toolbar to find all photos of a person in a second. You can combine several names separated with a comma to see photos, where all those people are presented together.
Another way to get photos with a specific person is to create a Smart Album with the face criteria to filter photos and find all photos with a person present. This album will update itself, and automatically add any confirmed photos of the person that may enter your collection in the future. It’s possible to set a few face names as criteria for a Smart Album in order to see photos where all those people are presented together.
OK, you got a little excited by Phototheca’s face-detection feature and tagged your annoying coworker Dave. Look, there he is on the Faces corkboard next to pictures of Dad. Oops! Keep calm —if you want to remove a face from the board, select it, and press Delete. The question appears, asking if you’re sure you want to remove the person from Faces. If you are, then click OK and wave goodbye. If you wish to zap multiple people off the wall at once, Ctrl-click each undesired person, and then press Delete. Again, Phototheca asks you to confirm your action.
Note: Deleting a face from the Faces corkboard do not delete any photos from your Phototheca library
Organizing the Faces Corkboard
Having your friends and family all lined up in Faces view gives you a great sense of organization. There are a couple of things you can do more about the organization of faces.
Change the key photo
The cover photo is the one that represents a person on your Faces corkboard; it’s typically the first one you tagged. If that photo doesn’t represent your friend’s character, there is a way to change it:
• Double-click the face shot to open up the album. Scroll through the album and select a photo you like better, right-click with a mouse and choose Make Cover Photo.
It’s easy to fix a typo or change the spelling of the name displayed on the corkboard cover photo. Just click the name, and the renaming box appears, letting you type whatever you want.
It may happen, after a few rounds of recognition or several imports, you ended by having more than one stack of faces for the same person. Phototheca gives the way to join(merge) them into a single stack. Just select a few stacks that belong to the same person, right-click with a mouse, and select “Merge…” to merge them into a single stack.
