Registration

MIL has a tool set for handling the registration or fusion of images for various objectives. A stitching tool is available for transforming images taken from different vantage points into a unified scene, which would be impractical or impossible to achieve using a single camera. It can also align an image to a reference for subsequent inspection. The tool contends with not only translation, but also with perspective, including scale. Alignment to a reference image or to neighboring images is performed with sub-pixel accuracy and is robust to local changes in contrast and intensity. In addition, the tool can be used for super-resolution where a sharper image is created from a series of images taken from roughly the same vantage point, which is useful for dealing with movement such as mechanical vibration.

Separate extended depth of field3 and depth-from-focus tools3 are on hand to produce, respectively, a single all-in-focus image and an index image from a series of images of a motionless scene taken at different focus points. The index image can subsequently be used to infer depth.

A photometric stereo tool is also available to produce an image that emphasizes surface irregularities—such as embossed or engraved features, scratches, or indentations—from a series of images taken with directional illumination as driven by a Light Sequence Switch (LSS) from CCS, a LED Light Manager (LLM) from Smart Vision Lights, or similar light controller.
