A 3-seat seating grouping is presented that includes a center seat configured for vertical translation from a lower position to a raised position when converted from an upright to an inclined mode. The center seat can be disposed between an aft-facing seating assembly and a fore-facing seating assembly, and be configured to overlap both when in a lie-flat position. Non-overlapping footspace can be shared between a center passenger and an aft-facing passenger. When upright, a center seat can be at the same height as a non-translating aft- or fore-facing seat, reducing loads on a seat track during aircraft take-off. Seats within the 3-seat group can be angled or aligned with respect to cabin longitudinal axis. A plurality of 3-seat groups can be combined in various orientations to span a cabin.

The present invention discloses a quick image registration method based on a visual remarkable area, which belongs to the field of image processing. The quick image registration method is used for matching an image A to be matched with a reference image B and respectively acquiring remarkable areas of A and B. The mass centers of three remarkable areas of A are vertexes of a triangle, and the triangle is used as a first characteristic triangle. Similarly a second characteristic triangle is acquired. The first characteristic triangle and the second characteristic triangle which are similar form a similar triangle pair, wherein the similarity of (a,b) is maximal. An affine transformation model for transforming from A to B is established based on (a,b), wherein the related initial matching parameters comprise horizontal translation amount, vertical translation amount, rotation angle and scale parameter. From the initial matching parameter, Powell searching for setting step length is performed for acquiring searching values. Each searching value is used for performing multiple registration tests on the A and B, and the searching value which corresponds with an optical registration test is the optimal matching parameter as a result. The optimal matching parameter is used for performing affine transformation on A for acquiring a final registration result.
