Abstract: Techniques for content-adaptive video sampling for automated video quality monitoring are described. As one example, a computer-implemented method includes receiving a request to train a machine learning model on a training video file comprising at least one labeled defect, performing an encode on the training video file to generate one or more compression features for each compressed frame of the training video file, training the machine learning model to identify a proper subset of candidate defect frames of the training video file based at least in part on the one or more compression features for each compressed frame of the training video file and the at least one labeled defect, receiving an inference request for an input video file, performing an encode on the input video file to generate one or more compression features for each compressed frame of the input video file, generating, by the machine learning model, a proper subset of candidate defect frames of the input video file based at least in part on the one or more compression features for each compressed frame of the input video file, and determining a defect in the input video file based at least in part on the proper subset of candidate defect frames of the input video file.

Abstract: Systems and methods are described herein for detecting image impairments indicating low quality images within video content. An image impairment detection (IMD) model can be generated with a training data set including images that include one or more image impairments. Video content comprising a set of video frames may be obtained and a video frame provided to the image impairment detection model as input. Output may be received from the image impairment detection model indicating that the video frame includes an image impairment artifact indicative of a particular image impairment. One or more operations may be executed based at least in part on the output received.

Abstract: Disclosed are various embodiments of systems and methods for receiving shipment parcels at, for example, materials handling facilities. In some embodiments, a parcel monitoring system detects an exception for a shipment parcel. The parcel monitoring system identifies a vendor associated with the shipment parcel. In response to the exception being detected, the parcel monitoring system controls a conveyor system in accordance with an action specified by an exception handling rule for the vendor.

Abstract: Techniques for systems and methods that provide for utilizing a robotic system to type commands that correspond to voice commands using a keyboard of a device are described herein. In embodiments, an image of a device may be received from a camera. A keyboard region of the device may be determined based on a keyboard detection algorithm that uses the image. One or more characters in a portion of the image that corresponds to the keyboard region of the device may be detected based on a character detection algorithm. The one or more characters may be grouped into one or more groups based on the portion of the image. A character of a portion of character associated with a group may be edited based on an error detection algorithm.
