Matrox Imaging Library (MIL) Tools


Stitching tool
Registration (Stitching)
MIL X 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.
Depth-from-focus tool
Registration (Depth-from-focus)
Separate extended Depth-of-field and Depth-from-focus tools 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.
Photometric Stereo tool
Registration (photometric stereo): Illumination (top, right, left, bottom), albedo and local shape results
A Photometric Stereo tool is offered to produce an image that emphasizes surface irregularities—such as embossed or engraved features, scratches, or indentations. The image is produced from a series of images of the same scene taken with directional illumination as driven by a Quad (X2) Controller from Advanced Illumination (Ai), Light Sequence Switch (LSS) from CCS, a LED Light Manager (LLM) from Smart Vision Lights, or similar light controller.
HDR tool
Registration (HDR): Short exposure, long exposure, result
An HDR imaging tool is also available to combine images of an identical scene, taken at different camera exposure levels, into a single image that contains a greater range of luminance.
