Abstract: The present disclosure provides a measurement method and system based on image electroencephalogram sensitivity data for a built environment dominant color, and relates to the field of urban quality measurement. The measurement method based on image electroencephalogram sensitivity data for a built environment dominant color includes acquiring electroencephalogram data corresponding to a built environment image sample; calculating an environment dominant color sensitivity on the basis of the electroencephalogram data; extracting a dominant color feature parameter according to the built environment image sample; constructing a built environment dominant color measurement model, and training same by taking sensitivity data and a dominant color feature as an input; and inputting an environment image to be analyzed into a trained model, so as to obtain a predicted dominant color sensitivity result. Therefore, the problems that a prediction effect of a nonlinear model integrating an image color feature and an environment quality is improved.

Abstract: Disclosed are a method, an apparatus and a storage medium for measuring the quality of a built environment. The method includes the following steps: identifying key influencing factors determining environmental quality, and establishing an index system of environmental quality influencing factors, wherein the key influencing factors include non-observation elements and observation elements; analyzing the relationship between the environmental quality and the key influencing factors to form a theoretical model; acquiring observation elements to form a large sample database; calculating path coefficients of each key influencing factor of environmental quality according to the distribution of sample data in the large sample database, and converting the path coefficients into weights; dividing distribution intervals of all observation elements dynamically according to the distribution of sample data, and defining quality assignments of all observation elements; and performing an environmental quality measurement of samples in combination with the weights and the quality assignments.

Abstract: The present invention discloses a method and an apparatus for extracting mountain landscape buildings based on high-resolution remote sensing images. The method comprises: segmenting a remote sensing image, and extracting non-vegetation areas from the remote sensing image by using NDVI; segmenting the non-vegetation areas, and extracting building areas by using NDBI; segmenting the building areas again, and calculating a normalized difference build shadow index NSBI of each patch; calculating NSBI separator of each patch in the non-vegetation areas and setting a separator threshold, and extracting landscape building areas based on the threshold. In the present invention, by introducing a near infrared band in the remote sensing image spectrum, in which there is a significant difference between shadows and non-shadows, the influence of large shadow areas in mountainous shady areas in the remote sensing image on the result of extraction is reduced.
