A template-based image analysis system and method are disclosed. A slide is loaded in a high-content image system (HCIS), wherein the slide includes a plurality of reference marks and a plurality of sample locations. An acquired images data store has previously acquired images stored therein. An image acquisition module acquires an image of the slide from the high-content imaging system. A feature identification module develops a binary image of the acquired image, wherein the binary image identifies areas associated with reference marks. A template generation module generates a template in accordance with the previously acquired images and a template alignment module aligns the generate template with the binary image. An offset calculation module determines an offset between the template and the binary image and an image segmentation module determines the coordinates of pixels of the acquired image that are associated with the sample locations in accordance with the calculated offset.

The invention relates firstly to a method for determining a mechanical deviation on a displacement path of an optical zoom lens (03), in particular on a displacement path of an optical zoom lens (03) of a microscope. The optical zoom lens (03) is arranged in a beam path (01) between an object (19) to be recorded and an electronic image sensor (04). In a first method step, an optical marker is introduced into the beam path (01) at a position of the beam path (01) located between the object (19) to be recorded and the optical zoom lens (03), such that the optical marker passes the optical zoom lens (03) and then is depicted on an image in which a position of the optical marker is detected and determined. This is compared with a reference position of the optical marker in order to determine the mechanical deviation on the displacement path of the optical zoom lens (03). The invention further relates to a method for correction of a displacement error of an image recorded by an electronic image sensor (04) and to an electronic image recording device.

Described are targets for use in optical tracking, as well as related methods. A target comprises a plurality of light dispersers, optically coupled to at least one light source. The light dispersers are illuminated for detection and tracking by a tracking system. In some implementations, the at least one light source is optically coupled to the plurality of light dispersers by a plurality of light directors. In other implementations, the at least one light source includes a plurality of light sources positioned within or proximate to the plurality of dispersers. In some implementations, dispersers are lenses; in some implementations, dispersers are light scattering elements. Targets include or are coupled to a power source. In some implementations, targets include additional electrical components which utilize power from the power source.

The present invention relates to target acquisition and related devices, and more particularly to telescopic gunsights and associated equipment used to achieve shooting accuracy at, for example, close ranges, medium ranges and long ranges at stationary and moving targets.

A deflection optical element, which diffracts incident light, includes a substrate having translucency, and a holographic material layer disposed so as to overlap the substrate, the holographic material layer being formed with a diffraction grating composed of interference fringes, wherein the holographic material layer is formed with an alignment mark where the interference fringes are discontinuous, and the alignment mark is located in an optically effective area where the holographic material layer diffracts the incident light.

In a method, it is determined that a detachable lens is mounted on an image capture device in a first orientation. A first image of a controlled scene is captured with the detachable lens mounted in the first orientation. It is determined that the detachable lens is mounted on the image capture device in a second orientation that is rotated approximately 180 degrees from the first orientation. A second image of the controlled scene is captured with the detachable lens in the second orientation. A first image circle center of the first image is determined. A second image circle center of the second image is determined. An average image circle center is determined, based on the first image circle center and the second image circle center. The average image circle center is provided to an image stabilization algorithm when the detachable lens is mounted on the image capture device.
