Hand Graph Representations for Unsupervised Segmentation of Complex Activities

Pratyusha Das, Jiun-Yu Kao, Antonio Ortega, Tomoya Sawada, Hassan Mansour, Anthony Vetro +1

ICASSP 2019accepted

Analysis of hand skeleton data can be used to understand patterns in manipulation and assembly tasks. This paper introduces a graph-based representation of hand skeleton data and proposes a method to perform unsupervised temporal segmentation of a sequence of sub-tasks in order to evaluate the effic…

Noise reduction for screen content coding based on local histogram

Kazuyuki Miyazawa, Akira Minezawa, Shun-ichi Sekiguchi

ICASSP 2015accepted

This paper proposes a noise reduction method for screen content coding using HEVC. The proposed method focuses on that the histograms of pixel values for screen content have distinct and sparse peaks respectively. This property is often degraded by the coding distortion, which arises some small peak…
