Latest Patents

One of Natsev's latest patents is focused on feature-based video annotation. This innovative system and methodology provide a way to annotate videos with entities and their associated probabilities of existence within video frames. The computer-implemented method identifies an entity from a range of characteristics and selects a set of features correlated with that entity. It also determines a classifier for the entity and an aggregation calibration function based on the selected features. This method ultimately assesses the probability of the entity's existence in a video frame.

Another notable patent involves selecting representative frames for video previews. This method includes receiving a video and identifying features for each frame, which encompass both frame-based and semantic features. The semantic features indicate the likelihood of certain concepts being present in the video frames. The method generates a score for each frame and selects a representative frame for each video segment based on these scores, effectively summarizing the content of the video.
