Association of Spatial Object Recognition and GEOBIA: an Experimental Approach

Spatial object recognition is an important facet of spatial information system. Psychological and mathematical basis are two important factors in forming spatial object. In recent years, Geographic Object Based Image Analysis (GEOBIA) is extensively used in extracting the information from remotely sensed images. The extracted information is being used by incorporating the experts’ knowledge. With these developments, in this paper, we conducted an experiment for the human subjects in an image of an area of natural importance. The image along with eight different sets of segmented images of the same area were provided to the human subjects, such that they can improve their understanding using their perception, cognition and decision for the Geographic object recognition. The results of two stages were collated and a relation to mathematical and psychological basis is made. The results showed that there exists different ways to comprehend the geographical objects according to background experience of human subjects, despite the use of similar automatic spatial partitions at different scales. But, also that there exists a certain association of pertinent scale to the human perception in recognising the spatial objects.
