However, since semantic objects in consumer photos and videos are usually captured in uncontrolled conditions, such as various viewpoints, positions, scales, and background clutter, in this talk, we will present sensing techniques for giving robust semantic object retrieval and recognition in real-world scenes. Two application scenarios will be showcased to demonstrate the effectiveness of the proposed sensing techniques. In particular, one application is mobile vision for locating the visual objects precisely and meanwhile achieving real-time performances. Another application is human action video search for users to create a search query by freely and continuously posing any number of actions in front of the Kinect sensor.
