Abstract
In hyperspectral images, spectral data can be combined with spatial details such as shape and texture for improved classification. Using a probabilistic platform, this paper proposes an approach for merging spatial (texture and shape) and spectral characteristics. Features of shape are extracted by MPs and fFeatures of texture are extracted by Gabor filters. The support vector machine (SVM) can classify these features separately, allowing an estimation of the probabilities for each pixel. To weigh integrations of these probabilities, the Developed Arithmetic Optimization Algorithm (AOA) has been developed. There are three parameters a, b, c that define how the features are effected in proposed integration. AOA calculates these parameters' optimal values. Pavia University, Indian Pines, and Salinas datasets are utilized to assess the proposed scheme. Classifying hyperspectral images using the proposed integration has been demonstrated to be effective, particularly with few labeled samples. Furthermore, comparing this method to some previously studied semi supervised classification approaches, it is more accurate.
