`“facial characteristic” / “characteristics of the face”
`
`PO’s Proposed Construction: “distinguishing element of a face,
`such as the nose, nostril, ears, eyebrows, mouth, etc.”
`
`Inconsistent with the specification
`
`“While the invention is being described with respect to identification
`of the nostrils as a starting point to locating the eyes, it is foreseen that
`any other facial characteristic, e.g., the nose, ears, eyebrows, mouth,
`etc., and combinations thereof, may be detected as a starting point
`for locating the eyes. These characteristics may be discerned from any
`characteristics capable of being searched by the system, including
`CO, DP, velocity, direction, luminance, hue and saturation.”

`
`39[d], [e]
`
`“selecting pixels of the portion of the image having
`characteristics corresponding to the feature to be detected” /
`“forming at least one histogram of the selected pixels”
`
`PO advances no construction, but argues these limitations require:
`• selecting “only iris, pupil, or cornea pixels”
`• “not merely selecting all the pixels in a particular area”
`
`Inst. Dec.: “We do not agree that the claim limitation … precludes
`selection of pixels that are not of the feature itself.… [C]laim limitation [d]
`… requires selection including pixels having characteristics corresponding
`to the feature, but it does not, however, limit selection to only those pixels
`and others could be included in the selection.”

`
`Eriksson selects pixels having “characteristics corresponding to the” pupil
`
`1. Luminance Characteristic: “In order to find the eye-regions given the proceeding
`processing, we rely on the fact that the eyes correspond to intensity-valleys in the
`image.”
`
`2. Positional Characteristic: Eriksson uses “general constraints, such that both eyes
`must be located fairly close to the center of the face”
`
`3. Relationship Characteristic: “We try to find a peak corresponding to a row in the
`image with two connected regions on.”
`• Uses vertical gradient histogram H(y): “Since both eyes are likely to be positioned
`at the same row, H(y) will have a strong peak on that row.”

`
`
`
`Obviousness Over Eriksson and Stringa
`
`It would have been obvious to combine Eriksson and Stringa
`• Both use histograms to identify a pupil.
`
`• Eriksson explicitly builds on Stringa.
`
`“One interesting application for face
`recognition was developed by Stringa
`[12]. He used the observation that the
`eyes are regions of rapidly changing
`intensity. We use a similar approach
`on a reduced version of the image.”
`
`“As suggested by Stringa
`[12], we use the observation
`that eye-regions correspond
`to regions of high spatial
`frequency.”

`
`
`
`Obviousness Over Eriksson and Stringa
`
`Contrary to PO’s argument, Eriksson and Stringa use histograms to
`identify the pupil, not template matching:
`
`“Our approach is different. It does not proceed by eye template matching. Rather, an
`algorithm is used based on the exploitation of (a priori) anthropometric information
`combined with the analysis of suitable grey-level distributions [i.e., “histograms”],
`allowing direct localization of both eyes.”
`
`Stringa (Ex. 1006) at 369 (emphases added).
`
`“[W]e need a robust way to determine if the eyes are open or closed; so we developed a
`method that looks at the horizontal histogram across the pupil.”

`Eriksson (Ex. 1005) at 317 (emphasis added).

`
`• This interpretation was rejected by the Board:
`Inst. Dec.: “We do not agree that the claim limitation … precludes selection
`of pixels that are not of the feature itself.… [C]laim limitation [d] … requires
`selection including pixels having characteristics corresponding to the feature,
`but it does not, however, limit selection to only those pixels and others could
`be included in the selection.”

`

`But the histogram is a necessary part of the process of

`Ando explains:
`“The threshold value THe . . . is determined from the histogram.”

`
`Contrary to PO’s argument, a POSA would seek to further increase Ando’s
`accuracy, which is admittedly imperfect:
`
`“This series of operations for detecting [the pupils and mouth] is repeated up to 8 times. If they cannot
`be detected in spite of 8 series of operations, the processes (l)-(8) are carried out to
`determine new threshold values . . . .” Ando (Ex. 1009) at 36:45–51.
`
`PO’s argument is irrelevant – Suenaga improves Ando by distinguishing between
`the eyebrow and eye and identifying blink rates, not by detecting the pupil
