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: 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.
