Thermal-image based object detection and heat map generation systems and methods
An infrared (IR) imaging module may capture a background image in response to receiving IR radiation from a background of a scene and determine background calibration terms using the background image. The determined background calibration terms may be scale factors and/or offsets that equalize the pixel values of the background image to a baseline, value. IR imaging device may use the background calibration terms to capture images that have the baseline value for pixels corresponding to IR radiation received from the background and higher values (or lower values) for pixels corresponding to IR radiation received from a foreground. Such images may be used to count people and generate a heat map. The background calibration terms may be updated periodically, with the update period being increased at least for some pixels or a pixel area when a person is detected.

Systems, methods, and computer-readable media are provided for machining a feature on a work piece along a curving tool path including a spiral pattern with continuously varying radius. In particular, the feature is scribed by a tool while varying an angle of rotation of a cutting surface of the tool with respect to the work piece to maintain a substantially constant angle between the cutting surface and a corresponding relative translational movement between the cutting surface and the work piece along the spiral pattern. A dynamic feed rate of the tool also is varied continuously with respect to the work piece based on the continuously varying radius of the at least one spiral pattern to substantially maintain a target centripetal acceleration of the tool with respect to the work piece.
