—The facial expression generation is one of the important issues of intelligent human-machine interface. It is of great challenge due to the complexity and mutability of the human face. Image-based facial expression generation techniques inherit naturally some features of images which are beneficial to reduce complexity and improve realism of expression(More)
In this paper, we tackle the problem of risk-averse route planning in a transportation network with time-dependent and stochastic costs. To solve this problem, we propose an adaptation of the A* algorithm that accommodates any risk measure or decision criterion that is monotonic with first-order stochastic dominance. We also present a case study of our(More)
AIM To investigate the minimally invasive ablation of giant osteoma of the ethmoid sinuses endonasally with the assistance of an image-guidance system. PATIENTS AND METHODS A retrospective analysis was carried out on 12 patients with osteomas of ethmoid sinuses treated by endoscopic surgery with the help of a navigation system from April 2005 to October(More)
CONCLUSIONS Although microvascular decompression (MVD), facial nerve splitting (FNS) and neurectomy procedures were safe treatments for hemifacial spasm (HFS), trigeminal neuralgia (TN) and glossopharyngeal neuralgia (GPN) in retrosigmoid cranial nerve surgery, fatal and severe complications may occur. It is essential to pay great attention to the entire(More)
The problems of moving object detecting and tracking on UAV (Unmanned Aerial Vehicle) platforms in surveillance operations are addressed, and a robust tracking method for reliably detecting and tracking of foreground moving objects in a dynamically changing environment is proposed. Firstly, using the modified robust local feature detector SURF (Speeded Up(More)
Neurogenic tumors located in the posterior mediastinum, generally require surgery which be confronted with greater risk,therefore, to design the best surgical approach and surgical methods is essential. A 67-year-old female patient had pharyngeal foreign body sensation and dysphagia. Thyroid ultrasound showed the right thyroid had a little nodule, and the(More)
