A method for automatic construction of 2D statistical shape models for the lung regions in chest radiographic images comprising: providing a radiographic image of the chest region of an individual; by performing a manual contour tracing, extracting the lung region shape instances from the chest radiographic image; by using a shape alignment algorithm, aligning all shape instances as closely as possible to a pre-defined template shape; and generating a statistical model shape of the lung regions by principle component analysis using the aligned shape instances.

A picture electrode of an MVA liquid crystal display device has a configuration where sub-picture electrodes are successively provided, while a cross-shaped slit is provided as an alignment restriction member on a common electrode of the side of a counter substrate. A columnar spacer is provided on a signal line of a TFT substrate in conformity to a position of a singular point of an alignment of liquid crystal molecules, the singularity occurring in a display region. This structure makes it possible, when a panel surface is depressed, to cause quick re-aligning of the liquid crystal molecules at the singular point of +1, as a base point, which has occurred at a center of the cross-shaped slit and in the vicinity of the columnar spacer, hence achieving a speedy recovery of displaying.

Apparatus and method for controlling the orientation of a fundamental panel vibration mode shape of a structure, such as a skin panel of a fuselage of an aircraft, relative to the direction of a turbulent boundary layer flow over the fuselage, and in a manner to achieve a level of noise reduction within the fuselage. The fuselage is constructed either through orientating stringers and / or frame members, or by using stiffening members placed diagonally between the stringers and frame members, in a manner that produces a fundamental panel vibration mode shape that extends at an angle of between about 30°-45° relative to the direction of the turbulent boundary layer flow over the fuselage. Aligning the fundamental panel vibration mode shape at an angle of between about 30°-45° relative to the direction of the turbulent boundary layer flow results in a reduction of the vibration response of the skin panel, and thus a reduction in the noise level within the fuselage.

A concrete column form aligning apparatus is useful for homeowners building decks, sheds or other structures or commercial builders making bridges, parking garages or other structures having column forms. The aligning apparatus comprises a plurality of platforms configured to engage a circumference of the concrete column form each having a securing device to fix and center each platform around the circumference of the concrete column form. Each of the apparatuses have at least one attachment bracket affixed at a predetermined angle, where the attachment brackets on each form linearly aligned at the proper angle with respect to the other attachment bracket on the other platform. A connector mechanism may be secured in the attachment bracket be using joining pieces at a designated length that secures and aligns the forms at the proper position.

The invention provides a three-dimensional human face sight line calculation method. A three-dimensional human face is accurately reconstructed, so that the sight line direction of the human face is accurately calculated. According to the method, a sight line direction calculation task is decomposed into two sub-tasks of sight line aligned three-dimensional face reconstruction and sight line contact realized through rotation. The method comprises the steps: reconstructing a basic three-dimensional face by using a three-dimensional deformation model and taking a two-dimensional reference face image as input; performing shape adjustment on the basic three-dimensional face to obtain a three-dimensional reconstructed face with an aligned shape so as to ensure that the eye region of the three-dimensional face is accurately aligned with the eye region of the input reference two-dimensional face image; and finally, acquiring the three-dimensional face with the aligned sight lines by replacing the texture of the eye region of the three-dimensional face with the aligned shape. For the sub-task of sight line contact, the invention provides a brand-new method for realizing sight line contact by rotating the three-dimensional face, and the method does not depend on excessive hypotheses and can be widely applied to the field of virtual reality.
