Semi-automated methods, including pixel and object-based image classification, demonstrate potential to accurately map vegetation communities, however, there is a lack of comparative research. This study is a component of a broader research project that compares several techniques and image datasets to ...
The two techniques proposed are: a) Maximum likelihood classifier used as pixel- based classification technique; and b) Image segmentation used as object-based classification technique. A study area covers an urban district in Burnaby, British Colombia, Canada, is selected to test the different ...
Aim of this study is to assess Support Vector Machine for efficiency and prediction for pixel-based image categorization as a contemporary reckoning intellectual technique. Support Vector Machine is a classification procedure estimated on core approaches that was demonstrated on very effectual in solving ...
Categorization based on objects is an effective way to integrate spectral and spatial information into remote sensing image classification. In this paper, we establish a classification framework which represents objects by super pixels. The non-parametric k-NN approach is chosen for this super pixel ...

An image can be segmented by classifying its pixels using local properties as features. Two intuitively useful properties are the gray level of the pixel and the ``busyness,'' or gray level fluctuation, measured in its neighborhood. Busyness values tend to be highly vari-able in busy regions;...
an interpolation method based on pixel classification is presented.The method classifies pixels of the image to be interpolated by the relativity of corresponding pixels of its neighbor original images.Then the different methods are adopted to interpolate the different points.In addition,error checkout ...

Land cover has undergone tremendous changes in the last century, with strong consequences on the environmental balance, therefore the classification of land cover using Earth Observation data is very important. Recently, the widely used pixel-based approach for land cover classification was questioned th...
