31 Aug 2017 Nearest neighbor classification is a powerful approach to classify segmented objects based on specific statistics and training samples chosen by the user. ideal image objects. As a rule of thumb, you want to produce image objects at the biggest possible scale, but still be able to discern between objects.
28 Feb 2017 compared and discussed and conclusions are made. In the end recommendations for further improvement and possible future research are given.

Nearest Neighbor object-based classifier results, and were found satisfac- tory. The SVM methodology seems the classification step can be implemented through logic rules and heuristics, operating on classes and . classifier used in eCognition, a.

There are two method of classification by remote sensing. Pixel-Based Classification will assign pixel to landcover. Object-Based will generate segments by integrating similar pixels at first, and then segments will be assigned to landcover. Object-Based Classification is suitable for classification based on high resolution
data, An object-oriented image analysis is implemented with the software eCognition. It is based on fuzzy logic set of knowledge-based classification rules to describe each class should be define. The rules includes spectral, spatial, contextual, and textual information. And then . REFERENCES. eCognition User Guide 4.

12 Nov 2013 Keywords: fuzzy rule based systems; object-based image classification; very high resolution satellite imagery . eCognition software. For multi-resolution image segmentation in eCognition, there are three .. 500 pixels) of each image is classified manually using human expertise. Then, using the manual.
Combining decision tree analysis with object- based classification has proven successful in arid rangelands. [7]. However, one disadvantage is that the decision tree analysis has to be performed outside of the image analysis program and rules derived from the tree have to be entered manually into eCognition.
