To face or not to face: Towards reducing false positive of face detection

2016 International Conference on Image and Vision Computing New Zealand (IVCNZ), 2016
We tackle the problem of reducing the false positive rate of face detectors by applying a classifier after the detection step. We first define and study this post classification problem. To this end, we first consider the multiple-stage cascade structure which is the most common face detection architecture.

Hallucinating face by position-patch

Pattern Recognition, 2010
A novel face hallucination method is proposed in this paper for the reconstruction of a high-resolution face image from a low-resolution observation based on a set of high- and low-resolution training image pairs. Different from most of the established methods based on probabilistic or manifold learning models, the proposed method hallucinates the high-

Position-based face hallucination method

2009 IEEE International Conference on Multimedia and Expo, 2009
In this paper, we propose a novel face hallucination method to reconstruct a high-resolution face image from a lowresolution observation based on a set of high- and lowresolution local training image pairs. Instead of basing on probabilistic or manifold learning models, the proposed method synthesizes the high-resolution image patch using the same ...

Surgical options in the face of positive pressure

Journal of Cataract and Refractive Surgery, 2006
Positive pressure during cataract surgery can adversely affect the clinical outcome if the surgeon is unprepared. A variety of surgical maneuvers are described, including dry insertion of the phacoemulsification needle, capsule protection with the second instrument, dry cortical aspiration in an ophthalmic viscosurgical device (OVD) environment ...

Face-to-Face Contact Method for Humanoid Robots Using Face Position Prediction

2019 14th ACM/IEEE International Conference on Human-Robot Interaction (HRI), 2019
It is an important functional behavior for humanoid robots to have face-to-face contact with humans. We predict future face position to achieve natural behavior that is similar to the communication between people. Robots gaze at a prediction point for reducing mechanical delay.

The Faces of Positive Emotion

Annals of the New York Academy of Sciences, 2003
Although several theorists posit the existence of multiple discrete positive emotion states,1–4 much empirical research on the nature and consequences of emotion considers only one: happiness.5–8 Studies of the facial display of emotion have documented universally recognized expressions of sadness, anger, fear, and other negative emotions, but have not

The Positive Face of Resistance

JONA: The Journal of Nursing Administration, 2006
To relate nurses' stories of their experiences of acts of resistance.Although resistance is often characterized as negative, it can be seen as a way that the less powerful speak up about workplace concerns. By studying how nurses resist, new perspectives about how some groups exercise power may be understood.For this qualitative study, 19 nurses were ...

Positive Transformation in the Face of Adversity

Academy of Management Proceedings, 2016
From workplace violence to lay-offs, people experience a variety of traumatic experiences at work. While there is clear evidence that employees suffer from these events, there is reason to believe that employees may also benefit from these travails.

Face Tissue Pressure in Prone Positioning

Spine, 2008
This is a prospective, randomized study.The purpose was to compare the tissue-pillow interface pressures at the forehead and chin in patients positioned in the prone fashion for spinal surgery on each of 3 facial positioners.Facial pressure ulcers have been infrequently observed after spinal surgery requiring prone positioning. This requires the use of
