1. Introduction In order to realize highly intelligent information processing systems which can recognize various objects in real-time/real-world, we have been proposed a concept of multi-object recognition system based on 3D custom stack system (3DCSS) presented in the 21st century COE of Hiroshima University [1]. Recently, we have developed a real time human face detection/recognition softwar...

b a c k ground: several studies have indicated that executive dysfunction is the main neuropsychological feature of parkinson’s disease (pd). the frontal assessment battery (fab) is a short tool for the assessment of executive functions. p u r p o s e : the aim of this study was to determine the relationship between persian version of fab scores and age, education, mini-mental state examination...

Ventral frontal cortex is commonly involved in traumatic brain injury (TBI). The smell identification test (SIT), object alternation (OA), and the Iowa gambling task (IGT) are associated with this brain region in experimental and neuropsychological research. We examined the relationship of performance on these tests to residual structural brain integrity quantified from MRI in 58 TBI patients, ...

introduction many conditions can mimic psychiatric symptoms. amongst them, intracranial mass and space occupying lesions have a significant importance. aggression and hallucination are seen in association with a basal frontal lesion, and may mimic psychotic syndromes. case presentation a 37-year-old man with no previous mental illness presented with a month history of headache, blurred vision, ...

This paper presents the indoor mobile robot that moves automatically without needing environment information beforehand while recognizing the frontal surrounding environment with only one general camera. Based on the frontal image, the robot detects two boundary lines, some obstacle regions, and a moving direction. When the obstacle is detected, the avoidance or stop movement is worked accordin...

AR markers are useful tool for easy recognition of pose and ID of target objects. However, they have poor accuracy in the orientation estimation, especially in the frontal direction. We solved the problem by a novel principle using variable moiré patterns. We developed two new AR markers which utilize moiré patterns of which the darkest part seems to move according to the visual-line angle of t...

We described a case of a 6 year old boy presenting with transient dizziness with weakness of left limbs. MRI showed the presence of a diffusely dilated extensive vascular lesion mainly located in the corpus callosum, right frontal and temporal lobes. Digital subtraction angiography (DSA) revealed a large hypervascular lesion with a diffuse arterial supply. 99mTc-ECD SPECT cerebral blood flow pe...

BACKGROUND AND PURPOSE For a better understanding of neuronal network disturbances after stroke, we investigated the changes in the cholinergic system after experimental focal infarct. METHODS We quantitatively evaluated the highly sensitive acetylcholinesterase histochemistry and local glucose utilization 7 days after left middle cerebral artery occlusion in Wistar rats. RESULTS In all rat...

Face detection is a key problem in building automated systems that perform face recognition/ verification, modelbased image coding, face tracking, and surveillance. Two algorithms for face detection based on either support vector machines or maximum likelihood estimation are described and their performance is tested on a collection of single images from the M2VTS database that depict one fronta...
