Abstract: According to examples, an apparatus may identify a first viewpoint that an entity expressed in a first media file, identify a second viewpoint expressed in a second media file that is attributed to the entity, determine that the second viewpoint is dissimilar to the first viewpoint and in response to the determination that the second viewpoint is dissimilar to the first viewpoint, may output a message.

Abstract: According to examples, an index of entries may be retrieved, in which each of the entries may correspond to phrases that are analogous to other phrases in content on a network. A plurality of phrases that are similar to the entries in the index may be identified in a content accessed on the apparatus and a determination may be made, based on a user interaction with the accessed content via a user interface, that the user has read a first phrase in the plurality of phrases. The index may be updated to indicate that the user has read the first phrase and, based on the updated index, a second phrase in a subsequently accessed content that is similar to the first phrase may be determined. In addition, the second phrase in the subsequently accessed content may be displayed differently from other displayed phrases in the subsequently accessed content.

Abstract: In some examples, a camera tracking failure in a simultaneous localization and mapping (SLAM) process with respect to a first SLAM map may be identified. Responsive to identification of the camera tracking failure, a second SLAM map for the SLAM process may be initialized. A video frame tracked through the second SLAM map may be accessed. Matched features between the video frame and individual keyframes of the first SLAM map may be identified to determine a keyframe subset. The keyframe subset may be analyzed to determine a candidate camera position from among the keyframe subset. The candidate camera position may be tracked with respect to the first SLAM map for subsequent video frames. The first SLAM map may be stitched to the second SLAM map responsive to tracking the candidate camera position with respect to the first SLAM map for the subsequent.
