Visual scalability is the capability of visualization tools effectively to display large data sets, in terms of either the number or the dimension of individual data elements. In this paper, we define and structure the problem of visual scalability, with special emphasis on the role of visualization as a means of access to details of the data. This is done abstractly in terms of responses that ...

Artificial Fish Swarm Algorithm (AFSA) is a kind of swarm intelligence algorithms which usually employs in optimization problems. There are many parameters to adjust in AFSA like visual and step. Through constant initializing of visual and step parameters, algorithm is only able to do local searching or global searching. In this paper, two new adaptive methods based on fuzzy systems are propose...

The mammalian visual system is endowed with a nearly infinite capacity for the recognition of patterns and objects. To have acquired this capability the visual system must have solved what is a fundamentally combinatorial problem. Any given image consists of a collection of features, consisting of local contrast borders of luminance and wavelength, distributed across the visual field. For one t...

background: parkinson's disease (pd) is a neurodegenerative disorder impairing motor, verbal and other abilities. visual evoked potential (vep) assessment is a useful method for analysis of visual system and its function. the present study was designed in order to evaluate whether vep changes are associated with pd. m aterials and methods: in the present study, 100 subjects encompassing 40 pati...

post cardiac surgery ophthalmic complications are uncommon, and sudden visual loss is one of the most important ophthalmic problems in these patients. we report a 54-year-old woman that suffered transient sudden bilateral visual loss seven days after orthotopic heart transplantation. in ophthalmologic examination positive findings were bilateral normal size pupils without direct and indirect pu...

Congenital deafness has a relationship with vestibular and motor functioning. However, many studies have focused on children rather than adults. This study compared the relationship of vestibular functioning and visual acuity between adult athletes who were deaf and their age-appropriate peers in order to understand differences in balance and vision. Specifically, balance capability, vestibular...

One of the major challenges in vision research is to analyze the effect of visual stimuli on human vision. However, no relationship has been yet discovered between the structure of the visual stimulus, and the structure of fixational eye movements. This study reveals the plasticity of human fixational eye movements in relation to the 'complex' visual stimulus. We demonstrated that the fractal t...

In the blind subterranean mole rat Spalax ehrenbergi superspecies complete ablation of the visual image-forming capability has been accompanied by an expansion of the bilateral projection from the retina to the suprachiasmatic nucleus. We have cloned the open reading frame of a visual pigment from Spalax that shows >90% homology with mammalian rod pigments. Baculovirus expression yields a membr...

This paper proposes the visual keywords to represent the visual appearance, such as color and texture, of regions in images without precisely image segmentation. Based on the proposed visual keywords, a multi-modal image query and retrieval (MIQR) approach is presented to retrieve desired images from image databases by using textual annotations associated with images and/or the proposed visual ...
