Abstract: A method for capturing and consolidating multi-spectral image data for regions of interest using one or more spectral boost mechanisms or techniques is disclosed. A first multi-spectral or hyperspectral workflow comprising time-stamped two-dimensional pixelated images of a region of interest is obtained by a first computer-enabled imaging device. Each of the images corresponds to image data captured for a respective frequency band of a plurality of frequency bands. First meta data is associated with the images of the first workflow and includes: a plurality of first positions and first orientations of the first imaging device indicating first positional and orientation data for the first imaging device, and indications of a respective frequency band for each of the images of the first workflow. A consolidated multi-spectral workflow for the region of interest is generated, which includes spectrally and spatially consolidating the images of the first workflow using the first meta data.

Abstract: Machine vision apparatus tracks a distinctive object in relation to a hazardous location on a work surface of a modified band saw in two, three, or four (3-D+T) dimensions, and calculates whether to send an “immediate shut-down signal” to the band saw. Cameras and an image processor are mounted on the band saw. The signal causes an integrated blade-arresting or stopping mechanism to immediately shift the idler wheel, removing blade tension and disconnecting the blade which is then braked to a complete, safe stop before an approaching blue-gloved hand can touch the blade.
