Measuring linear separations in digital radiographs

Digital pixel data is obtained from radiographic imaging of one or more objects, and corresponds to an imaged area containing a feature to be measured. A data profile for a region around the measured feature is created from the digital pixel data. A reference profile is then created from the data profile. The reference profile represents an expected data profile for a reference condition of the objects, and accounts for the point spread function of the imager. The difference between the data profile and the reference profile is calculated. Based on that difference, the degree by which the actual condition of the objects varies from the reference condition is determined. The calculated difference can be compared to a lookup table mapping previously calculated differences to degrees of variation from the reference condition. The calculated difference can also be used as an input to an experimentally derived formula.

Nested pair of blanks

The invention relates to a nested pair of blanks on a unitary sheet which minimizes the amount of scrap sheet material (i.e., sheet scrap) upon separation of the blanks and construction of containers formed from the blanks. The nested pair of blanks provides a first blank for forming a container, a second blank for forming an identical container, and a non-linear separation interface that connects the first and second blanks to one another in a rotationally inverted relationship. The nested configuration reduces the amount of sheet scrap in the sheet. The invention further relates to a container formed from the first or second blank having features that reduce sheet scrap and offset the potential weakening of the container bottom resulting from reduced overlapping sheet material.

Surface defect judging method

A decision algorithm of discriminating a defect type and / or a defect level is automatically produced in a short time. The accuracy of defect classification in terms of a defect type or a defect level is improved. More specifically, feature values of surface defects acquired in the past are represented as points in a feature space, constraint is set that when the feature space is mapped into a space by an assumed mapping function, a discriminant plane can be defined in the mapped space such that mapped feature values are linearly separable perfectly with respect to the discriminant plane, an objective function is defined as the distance between the discriminant plane and a point located closest to the discriminant plane, an optimal discriminant plane is determined by solving a quadratic programming problem such that the objective function is maximized under the constraint, the determined discriminant plane is employed as a discriminant function, a feature value of a surface defect whose type is unknown is substituted into the discriminant function, and it is determined, from the resultant value of the discriminant function, whether the surface defect whose type is unknown is of the particular surface type.
