In this paper, we focus on face clustering in videos. Given the detected faces from real-world videos, we partition all faces into K disjoint clusters. Different from clustering on a collection of facial images, the faces from videos are organized as face tracks and the frame index of each face is also provided. As a result, many pair wise constraints(More)
We describe a novel method that simultaneously clusters and associates short sequences of detected faces (termed as face track lets) in videos. The rationale of our method is that face track let clustering and linking are related problems that can benefit from the solutions of each other. Our method is based on a hidden Markov random field model that(More)
This work focuses on the problem of multi-label learning with missing labels (MLML), which aims to label each test instance with multiple class labels given training instances that have an incomplete/partial set of these labels (i.e. some of their labels are missing). To handle missing labels, we propose a unified model of label dependencies by constructing(More)
Many problems in computer vision, such as image annotation, can be formulated as multi-label learning problems. It is typically assumed that the complete label assignment for each training image is available. However, this is often not the case in practice, as many training images may only be annotated with a partial set of labels, either due to the(More)

A power assist walking leg is designed for enhancing strength and endurance during walking, it can be also applied to one whose legs are injured or who has difficulty in walking because of aging, paralysis and amputation. In this paper, we intend to introduce a concept of power assist walking support system and its fundamental control strategy using the(More)
In this paper, we intend to introduce a concept of power assist walking support system and a fundamental strategy of walking support using human-robot interaction force information. The work presented is developing a mechanism, which is in physical contact with the human body, with goal of decreasing human inner force/increasing human strength during a(More)
