Hierarchical Video Generation from Orthogonal Information: Optical Flow and Texture
Katsunori Ohnishi, Shohei Yamamoto, Yoshitaka Ushiku +1
Learning to represent and generate videos from unlabeled data is a very challenging problem. To generate realistic videos, it is important not only to ensure that the appearance of…
Beyond Caption To Narrative: Video Captioning With Multiple Sentences
Andrew Shin, Katsunori Ohnishi, Tatsuya Harada
Recent advances in image captioning task have led to increasing interests in video captioning task. However, most works on video captioning are focused on generating single input o…
Improved Dense Trajectory with Cross Streams
Katsunori Ohnishi, Masatoshi Hidaka, Tatsuya Harada
Improved dense trajectories (iDT) have shown great performance in action recognition, and their combination with the two-stream approach has achieved state-of-the-art performance.…
Dense Image Representation with Spatial Pyramid VLAD Coding of CNN for Locally Robust Captioning
Andrew Shin, Masataka Yamaguchi, Katsunori Ohnishi +1
The workflow of extracting features from images using convolutional neural networks (CNN) and generating captions with recurrent neural networks (RNN) has become a de-facto standar…
Recognizing Activities of Daily Living with a Wrist-mounted Camera
Katsunori Ohnishi, Atsushi Kanehira, Asako Kanezaki +1
We present a novel dataset and a novel algorithm for recognizing activities of daily living (ADL) from a first-person wearable camera. Handled objects are crucially important for e…
