Abstract: A method includes receiving, at a conference endpoint, video captured using a wide angle lens. The method further includes selecting a view region in a frame of the video. The method further includes selectively applying, based on a size of the view region, deformation correction or distortion correction to the view region to generate a corrected video frame. The method further includes transmitting the corrected video frame to a remote endpoint.

Abstract: A first machine learning model is applied to an image of a person and a stationary object to generate a first intermediate image including a simplified pose representation of the person in the image corresponding to a pose of the person. A simplified representation of the stationary object in the image is added to the first intermediate image. The simplified representation includes key points of the stationary object in the image. A second machine learning model is applied to a second intermediate image corresponding to the first intermediate image to determine a state of the person relative to the stationary object in the image as either a first state or a second state.

Abstract: A parts packing method is used to optimize build bed part placement for additive manufacturing. The method includes a user interface to parts packing software, enabling a process engineer to select parts from a pool of parts, group parts to have uniform orientation, and specify a range of angles and rotation of the parts. Additionally, the user interface accepts input related to process variations among different printers as well as drift over time of a single printer. The user interface feeds the data into the parts packing program to optimize build bed part placement.

Abstract: In an example, a method includes obtaining, by processing circuitry, a mapping from at least one measured color characteristic of a first substrate to at least one measured color characteristic of a second substrate, wherein the at least one measured color characteristic of the first substrate comprises a measured color characteristic of an unmarked portion of the first substrate and the at least one measured color characteristic of the second substrate comprises a measured color characteristic of an unmarked portion of the second substrate. In some examples the method further includes applying, by processing circuitry, the mapping to a first color which is obtained when applying at least one colorant according to a first colorant specification on the first substrate to determine a predicted color to be obtained by applying at least one colorant according to the first colorant specification on the second substrate.

Abstract: A device includes a display panel and a processor. The processor is to receive information corresponding to an image displayed on the display panel and determine whether a relevant portion of the image is centered with respect to an area of interest of the display panel. The processor is further to responsive to a determination that the relevant portion of the image is not centered with respect to the area of interest of the display panel, perform an operation to cause the relevant portion of the image to be adjusted such that the relevant portion of the image is centered with respect to the area of interest of the display panel.

Abstract: In one example, the tension in a print media may be determined in a region between a roller for unwinding the print media and a print zone. In this example, the rotational speed of the roller may be controlled based on the determined tension of the print media.

Abstract: In examples, an electronic device comprises a bus and a microcontroller coupled to the bus. The microcontroller is to encode a pattern in a pulse width modulated (PWM) signal by manipulating a duty cycle of the PWM signal and a duration of the duty cycle and to provide the PWM signal on the bus. The electronic device comprises a display panel and a timing controller (TCON) coupled to the display panel and to the microcontroller via the bus. The TCON is to control a brightness feature and a non-brightness feature of the display panel based on the pattern encoded in the PWM signal.
