Abstract
In the case of collecting samples, it is difficult to select a representative point of a target area. Thus, the samples are collected from certain positions, resulting in generation of variations of data. The target area is specified on an image to extract features from the target area. Further, clustering is performed for the features on a feature space to obtain representative features, and the obtained representative features are extracted as sampling points.
Claims15
A sampling position-fixing system comprising:
- an inputting unit that inputs image data as an analyzing target;
- an image correlating unit that correlates the image data with map data;
- a unit that extracts features of the image data correlated with the map data by the image correlating unit;
- a unit that performs clustering for the extracted features on a feature space and spatially analyzes a clustering result;
- a unit that extracts representative points from the spatially-analyzed image;
- and
- an outputting unit that outputs the extracted representative points as sampling positions.
