The effect of input data transformations on object - based image

چکیده
2 The effect of using spectral transform images as input data on segmentation quality and 3 its potential effect on products generated by object-based image analysis are explored in the 4 context of land cover classification in Accra, Ghana. Five image data transformations are 5 compared to untransformed spectral bands in terms of their effect on segmentation quality 6 and final product accuracy. The relationship between segmentation quality and product 7 accuracy is also briefly explored. Results suggest that input data transformations can aid in 8 the delineation of landscape objects by image segmentation, but the effect is idiosyncratic 9 to the transformation and object of interest. 10

Object-Based Classification of UltraCamD Imagery for Identification of Tree Species in the Mixed Planted Forest
This study is a contribution to assess the high resolution digital aerial imagery for semi-automatic analysis of tree species identification. To maximize the benefit of such data, the object-based classification was conducted in a mixed forest plantation. Two subsets of an UltraCam D image were geometrically corrected using aero-triangulation method. Some appropriate transformations were perfor...

متن کاملSegmentation Assisted Object Distinction for Direct Volume Rendering
Ray Casting is a direct volume rendering technique for visualizing 3D arrays of sampled data. It has vital applications in medical and biological imaging. Nevertheless, it is inherently open to cluttered classification results. It suffers from overlapping transfer function values and lacks a sufficiently powerful voxel parsing mechanism for object distinction. In this work, we are proposing an ...
