Feature selection is becoming a major component of object-based classification as numerous features of segmented object become available. Although common feature selection methods in object-based classification are acknowledged, wrapper-based methods remain an issue due to the diversity of accuracy assessment methods. This letter presents a new wrapper approach using polygon-based cross validation...
In this paper three images of Landsat TM data of 1983, 1999 and 2010 in winter being used to analyze the land cover changes in Lushan and surrounding areas. This paper classified the land cover types into 7 classes as cultivated land, grass land, forest land, sand, water, construction land and unused land by maximum likelihood classification, then analyses the land cover change. The results show that...
This paper studied on shadow detection method on high resolution remote sensing image based on HIS space transformation and NDVI index. Firstly, the high resolution remote sensing image was transformed to HSI space, and the shadow of image could be detected with the characteristics of the low brightness and the high saturation in the area of shadow. Then according to the NDVI index of image, some...
