Abstract: A content analyzer determines whether various types of modification have been made to images. The content analyzer computes JPEG ghosts from the images that are concatenated with the image channels to generate a feature vector. The feature vector is provided as input to a neural network that determines whether the types of modification have been made to the image. The neural network may include a constrained convolution layer and several unconstrained convolution layers. An image fake model may also be applied to determine whether the image was generated using a computer model or algorithm.

Abstract: Various client devices include displays and one or more image capture devices configured to capture video data. If a user is exchanging content with another user via a client device and is subsequently identified by a receiving client device via image data captured by an image capture device of the receiving client device, the client device transfers the exchanged content with the other user to the receiving client device. The receiving client device includes information identifying one or more other client devices authorized to transfer exchanged content to the receiving client device when the receiving client device receives a request from the client device. If multiple other client devices are within a threshold distance of the receiving client device, the other client devices transfer exchanged content to the receiving client device, which combines the content from different other client devices.

Abstract: An audio system includes a transducer assembly, an audio sensor, and a controller. The transducer assembly is coupled to a back of an auricle of an ear of the user. The transducer assembly vibrates the auricle over a frequency range to cause the auricle to create an acoustic pressure wave in accordance with vibration instructions. The acoustic sensor detects the acoustic pressure wave at an entrance of the ear of the user. The controller dynamically adjusts a frequency response model based in part on the detected acoustic pressure wave, updates the vibration instructions using the adjusted frequency response model, and provides the updated vibration instructions to the transducer assembly.

The etch mask includes an outer area near an edge of the etch mask. A width of the outer area defined by a distance from the edge of the etch mask is less than 100 ?m. A duty cycle of the etch mask in the outer area changes gradually between at least 10% and at least 90%.

Abstract: An online system may identify content with which a user has an interest. For example, the online system may determine that a user has an interest in the content based on interaction information indicating that the user interacted with the content. In a particular example, the online system may identify image concepts included in the content based on computer vision techniques that recognize the image concepts. The online system may model probabilities that image concepts will appeal to users. Based on the modeled probabilities, the online system may automatically recommend image concepts for inclusion in candidate images, automatically generate candidate images, or assess candidate images to determine a probability of user interaction with the assessed candidate images.

Abstract: An online system is configured to recommend a live video to a target user by presenting the live video in the target user's newsfeed or other location. The online system receives a plurality of live videos for streaming to its users. To recommend a live video, the online system dynamically identifies a topic of each of the plurality of live videos during the streaming. The online system further selects a group of candidate live videos, each of which has an identified topic matching an interest of the target user. The online system ranks the candidates based on a probability that the target user would positively interact with each candidate live video if the candidate live video is presented to the target user. Then the online system provides a candidate above a threshold level in the ranking for display to the target user, e.g., in a newsfeed of the target user.

Abstract: An online system receives an advertisement request (“ad request”) including an advertisement from a user and allows the user to create an alternative advertisement for the ad request comprising images presented in an order specified by the user. The online system may identify images from video data included in the ad request or from additional content associated with an object associated with the ad request. Based on selections of identified images by the user and an order in which to present the selected images from the user, the online system generates the alternative advertisement and associates the alternative advertisement with the ad request. One or more criteria are associated with the alternative advertisement, and the online system communicates the alternative advertisement to client devices having characteristics satisfying the criteria rather than video data in the advertisement.
