摘要： A method and apparatus for estimating a position of an access point (AP) includes (a) measuring a strength of a signal, transmitted by the AP, at three or more measurement points (MPs), (b) selecting an imaginary attenuation factor, (c) calculating a range between the AP and each of the MPs on the basis of the imaginary attenuation factor and a strength of a signal measured at the MP, (d) calculating an intersecting point of ranging circles in each of which a position of the MP is a center and the range between the MP and the AP is a radius, (e) calculating a best intersecting point from among a plurality of the intersecting points obtained by repeating the steps (c) and (d) while changing the imaginary attenuation factor, and (f) estimating the best intersecting point as the position of the AP.

摘要： Methods and systems for processing an image are described. A saliency map is generated from the image. The saliency map indicates one or more salient portions of the image that have saliency values satisfying a saliency criterion. A scene graph is generated for at least the one or more salient portions. The scene graph represents a plurality of objects detected in the image. The scene graph further represents one or more relationships between each respective object pairs. One or more dataset entries associated with the image are generated. Each of the one or more relationships for each of the one or more object pairs is indicated by a respective dataset entry. The one or more dataset entries are stored in a first dataset.
