In this paper, a novel classification processing based on the spatial information and the concept of Adaboost for hyperspectral image classification is proposed. This classification process is named as adaptive feature extraction with spatial information (AdaFESI). The main idea is adaptive in the sense that subsequent feature spaces are tweaked in favor of those instances misclassified by spectral or spatial classifiers in the previous feature space. All training samples are projected into these feature spaces to train various classifiers and then constitute a multiple classifier system. The experimental results based on two hyperspectral data sets show that the proposed algorithm can generate better classification results.

The objective of this study was to develop a computerized test of prone extension to measure performance of prone extension in children 4 to 6 years of age. The participants were selected from kindergartens, comprising 132 boys and 107 girls with a mean age of 5 yr. 2 mo. (SD = 6 mo.). Sensitivity and specificity of the computerized test of prone extension were assessed by comparison with the judgments of an expert, an occupational therapist with more than 20 yr. of pediatric experience, as the criterion standard. The computerized test of prone extension identified children with poor outcomes with a sensitivity of 0.83, a specificity of 0.88, and an accuracy of 0.87. The internal reliability index was 0.81. The computerized test of prone extension could be of value in detecting problems of antigravity posture in prone extension and permitting early intervention to correct it.
