摘要： According to some embodiments, an image processor includes a perspective image generator, a perspective image acquirer, a corresponding point acquirer, a first calculator and a display image generator. The first calculator updates the position of the one or more first corresponding point on the first perspective image, based on a difference in position between the first and second perspective images. The display image generator generates a first display image including the first and second perspective images, the one or more first corresponding points updated on the first perspective image, and the one or more second corresponding points on the second perspective image. The perspective image generator changes the first direction into a third direction based on the difference in position between the first and second perspective images, and generates an updated one, viewed in the third direction, of the first perspective image.

摘要： According to one embodiment, a defect inspection apparatus includes a storage and a processor. The storage stores dictionary in which a first design image generated by software is associated with a first real image corresponding to the first design image. The processor acquires a second design image generated by the software. The processor searches for a similar first design image similar to the second design image. The processor generates a reference image that is a pseudo real image of a second inspection object, based on the second design data and free of defect, by using the first real image associated with the similar first design image. The first design image includes information of an image area wider than the first real image.

摘要： A medical image processing apparatus of an embodiment has acquisitor, a first landmark detector, and an estimator. The acquisitor acquires a perspective image of an object to be treated imaged by an imaging apparatus. The first landmark detector detects a position of a landmark that appears in the perspective image acquired by the acquisitor. The estimator, based on relationship information indicating a relationship between the position of landmark and the position of a target, estimates the position of the search-for location of the object to be treated from the position of the landmark detected by the first landmark detector.
