PALACIO DE LA ALMUDAINA

As mentioned earlier, the initial (ambitious) goal was to have 500 subjects enrolled in the DISGUISEDFACEDATABASE, with at least half returning for a second session. Due to the

number of sessions we wanted to run, and the time constraints (the room used for capture was only available to us for 7 months), we knew that the process of recording a session

would need to be as streamlined as possible.

For this reason, it was not feasible to include all 164 possible combinations2 _{of the six}

disguise components. Instead, we chose what we believe to be a representative sample, which includes the six disguise components on their own (including their variations), as well as 12 disguises that use multiple disguise components. All of the disguises can be seen in capture order in AppendixA, alongside their abbreviations.

The disguises were broken up into “sets” to streamline the capture session. A large part of streamlining the sessions was deciding the number of disguise combinations and the order in which they would be applied. We kept in mind that adhesive and difficult to adjust disguises should not be moved or replaced more than necessary, that disguises should not be taken off unnecessarily, and that it would not be possible to capture every disguise combination.

We describe the 28 chosen disguises and disguise combinations in detail below. Addi- tionally, between many of the sets, “clean” images of the subject were also taken, in which the subject wore no disguise. These shots differ from the original shot taken of the subject in their street clothes, as all facial accessories were removed and the subject wore a lab coat for the clean shots.

Surgical Face Mask

The first disguise set was the surgical face mask disguise set, which consisted of (1) the surgical face mask disguise applied normally This was followed by (2) the top third of the mask being folded down (exposing the nose), and finally (3) folding up the bottom third of the mask (exposing the chin in addition to the nose). During the remainder of the session,

2_{To compute this number, we break the face down into three sections; two disguises that cover the same}

area of the face cannot be worn at once. For the top of the head, there are two possibilities (baseball hat, baseball hat backwards); for the eye area, there are 10 possibilities (the four sunglasses, the domino mask, and the five ways of wearing the eyepatch); for the mouth area, there are four possibilities (three ways of wearing the surgical mask, and the mustache). Add to this the option of leaving each area undisguised, and we have 3 * 11 * 5 = 165 combinations. This total includes the face undisguised, and removing that leaves a total number of 164 disguise combinations.

when used as part of a disguise the face mask was worn normally, with both the nose and chin covered.

Eyepatch

The eyepatch disguise set was second, and began with the adhesive eyepatch being used to cover (1) the subject’s right eye (and eyebrow), followed by covering (2) their left eye (and eyebrow). After both eyes were covered individually, we cut the eyepatch in half, and used the halves to cover the eyebrows independently. We first covered (3) the subject’s right eyebrow; we then added the other half of the eyepatch to the left eyebrow, covering (4) both of the subject’s eyebrows. We asked the subject to again wear (5) the surgical face mask while both eyebrows were covered. Following that, the face mask was removed and the right eyebrow was uncovered, allowing us to take a picture with only (6) the subject’s left eyebrow covered.

Sunglasses

The third disguise set was the sunglasses disguise set, and consisted of the subject first wearing all four sunglasses individually. In order, they were: (1) black frames with dark lenses, (2) black frames with clear lenses, (3) white frames with dark lenses, and (4) white frames with clear lenses. We then had the subject wear (5) the black frames with dark lenses together with the surgical face mask, with the mask situated underneath the glasses where they overlapped. For the remainder of the session, when sunglasses were used as

part of a disguise, the subject wore the black frames with dark lenses.

Baseball Hat

Directly following the sunglasses set was the baseball hat disguise set, which began by adding a hat to the last disguise the subject wore, creating a disguise that combined (1) the baseball hat, sunglasses (black frames with dark lenses), and face mask. Following that, we removed the sunglasses, leaving only (2) the hat and face mask. We then removed the face mask and added the sunglasses back, for a disguise consisting of (3) the hat and sunglasses.

Finally we removed the sunglasses, giving a shot of just (4) the baseball hat. Following this, we had the subject wear (5) the hat backwards.

Domino Mask

The fifth disguise set was the domino mask disguise set, which began by having the subject put on and adjust (1) the domino mask so that their eyes were visible to the cameras. Following this, the subject added (2) the face mask to the domino mask (over the domino mask in cases where there was overlap), being careful not to move the domino mask. To

this we also added the baseball hat, for a disguise combining (3) the hat, domino mask, and face mask3_{. A final shot was taken after having the subject remove the face mask, leaving}

just (4) the hat and domino mask.

Mustache

The mustache disguise set was the final set, and began by applying a mustache (chosen at random from the available styles) to the subject’s face. Once a shot was captured of (1) the

3_{This disguise was not originally included in the capture design, and is missing from the first 32 capture}

mustache, we added the domino mask, again having the subject adjust the mask. After a shot was taken of (2) the domino mask and mustache, the domino mask was removed, and the baseball hat was added, allowing capture of (3) the hat and mustache. To this, we also added the sunglasses, creating a disguise of (4) the hat, sunglasses, and mustache. We then removed the hat, for a final shot of (5) the sunglasses and mustache.
