摘要： A plurality of cameras is placed so that those optical axes become parallel to the Z-axis and are in relative position t on the XY plane. Multi-view video compression coding apparatus determines depth distance Z and unit normal vector (nx, ny, nz) of the arbitrary point in the surface of the object, moves the first block by disparity vector based on t and Z, transforming the first block by linear transformation matrix based on t, Z and n, then, matching the first block to block of the second picture. Then, while changing Z and n arbitrarily, the second block of the second picture which is most similar to the first block is searched for.

摘要： The present invention provides a method of generating a virtual viewpoint video image when the virtual viewpoint position is not located on a plane where a camera is disposed. In an environment in which a plurality of cameras having a horizontal optical axis are disposed in a real zone (for example, on the circumference) which surrounds an object, a video image of an arbitrary viewpoint on the circumference is generated. Further, by synthesizing video images photographed by a camera, a free viewpoint video image is generated from a virtual viewpoint (viewpoint from a high or low position) where no camera is placed. According to a method of achieving this, a travel distance of a display position is calculated by the local region synthesizing portion and this travel distance is reflected to the free viewpoint video image of a local region.

摘要： Apparatus and method evaluate a wafer fabrication process for forming patterns on a wafer based upon design data. Within a recipe database, two or more inspection regions are defined on the wafer for analysis. Patterns within each of the inspection regions are automatically selected based upon tendency for measurement variation resulting from variation in the fabrication process. For each inspection region, at least one image of patterns within the inspection region is captured, a reference pattern, represented by one or both of (a) one or more line segments and (b) one or more curves, is automatically generated from the design data. An inspection unit detects edges within each of the images and registers the image with the reference pattern. One or more measurements are determined from the edges for each of the selected patterns and are processed within a statistical analyzer to form statistical information associated with the fabrication process.
