FEATURE IDENTIFICATION OR CLASSIFICATION USING TASK-SPECIFIC METADATA

摘要

Innovations in the identification or classification of features in a data set are described, such as a data set representing measurements taken by a scientific instrument. For example, a task-specific processing component, such as a video encoder, is used to generate task-specific metadata. When the data set includes video frames, metadata can include information regarding motion of image elements between frames, or other differences between frames. A feature of the data set, such as an event, can be identified or classified based on the metadata. For example, an event can be identified when metadata for one or more elements of the data set exceed one or more threshold values. When the feature is identified or classified, an output, such as a display or notification, can be generated. Although the metadata may be useable to generate a task-specific output, such as compressed video data, the identifying or classifying is not used solely in production of, or the creation of an association with, the task-specific output.

主权项

1. A computer system providing a feature identification or classification tool for analyzing measurements taken by a scientific instrument, the computer system comprising a video encoder configured to perform operations associated with video encoding and a metadata capture component configured to capture metadata generated by the video encoder, to facilitate identification or classification of a feature of the measurements taken by the scientific instrument, wherein the computer system is configured to perform operations comprising:
receiving source video data comprising frames, at least one of the frames depicting, or associated with, the feature of the measurements taken by the scientific instrument; with the video encoder, performing operations associated with video encoding on the source video data to produce video encoder metadata, the video encoder metadata indicating decisions or observations made by the video encoder for production of encoded video data; with the metadata capture component, capturing at least a portion of the video encoder metadata to produce captured metadata; and with the metadata capture component, providing the captured metadata to facilitate identification or classification, based on the captured metadata, of the feature of the measurements taken by the scientific instrument.
