Spatial Encoding Using Differences of Global Features
While histogram or global feature approaches are powerful methods to encode image information for retrieval purposes, they suffer from a complete lack of spatial information. One possibility to reduce this shortcoming is to store feature vectors of subregions. However, this procedure increases the size of the index vector. The paper suggests to store only the differences of the features between...
متن کاملSpatial Representation of Environmental and Geographical Space in Different Perspectives
This experiment investigates the impact of scale and perspective on spatial representations. Seventy summer school participants indicated the spatial relationship between the conference center and a nearby lake (map A) as well as their hometown (map B). They marked the target both on partial maps in birds-eye perspective or on a tilted plane (oblique perspective). After completing both maps, pa...
متن کاملSpatial encoding in mountain chickadees: features overshadow geometry.
Encoding the global geometric shape of an enclosed environment is a principal means of orientation in human and non-human animals. Animals spontaneously encode the geometry of an enclosure even when featural information is available. Although features can be used, they typically do not overshadow geometry. However, all previously tested organisms have been reared in human-made environments with...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Differential Encoding of Spatial Information among Retinal ON Cone Bipolar
29 The retina is the first stage of visual processing. It encodes elemental features of visual 30 scenes. Distinct cone bipolar cells provide the substrate for this to occur. They encode visual 31 information, such as color and luminance, a principle known as parallel processing. Few studies 32 have directly examined whether different forms of spatial information are processed in parallel 33 am...
