| Abstract | This paper evaluates the influence of segmentation by multiresolution and quadtree algorithm on automatic supervised classification of high spatial resolution satellite images with and without histogram equalization for crop coffee classification. The study area was the municipality of Machado (MG) and in this work were used rapideye images because of its high spatial and radiometric resolutions. The crop coffee plants because of its intrinsic characteristics is easily can be confused with savanna vegetation in automatic classification process because of their similar spectral response. The use of segmentation techniques allows the use of shape and texture features, yet the spectral ones. The study area had two images with two different angle looks at the same time, which implied in different responses for each sensor because of the non lambertianity of the objects. For each class training samples were collected and the thematic result image was got through the nearest neighbor classifier applied to its segments. The effects of the histogram equalization were measured by comparing the classification results with and without histogram equalization to the reference image classified manually by trained professional, getting the global and kappa indices. Also were done a comparison between the results of multiresolution segmentation and quadtree segmentation. Multiresolution have produced more adequate segments to the contours of the coffee plants objects, with homogeneous contents, while quadtree generated too many segments, not capturing border areas. Histogram equalization showed itself an important pre-processing step on image classification process, influencing in the accuracy. |
