WebNov 28, 2024 · In addition to the spectral and textural features, the spatial features were also used in the image classification. The spatial features include area index, density index, rectangular fit, elliptic fit, asymmetry, compactness, border index, and shape index. Overall, there are 66 different features for the three types of features described above. WebeCognition classifies and analyzes imagery, vectors and point clouds using all the semantic information required to interpret it correctly. Rather than examining stand-alone pixels or points, it distills meaning from the objects' connotations and mutual relationships, not only with neighboring objects but throughout various input data.
Rule sets are a combination of single processes, which are displayed in the Process Tree and created using the Edit Process dialog box.
