TL;DR: This paper presents a novel approach to unsupervised change detection in multispectral remote-sensing images by using a selective Bayesian thresholding for deriving a pseudotraining set that is necessary for initializing an adequately defined binary semisupervised support vector machine classifier.
Abstract: This paper presents a novel approach to unsupervised change detection in multispectral remote-sensing images. The proposed approach aims at extracting the change information by jointly analyzing the spectral channels of multitemporal images in the original feature space without any training data. This is accomplished by using a selective Bayesian thresholding for deriving a pseudotraining set that is necessary for initializing an adequately defined binary semisupervised support vector machine classifier. Starting from these initial seeds, the performs change detection in the original multitemporal feature space by gradually considering unlabeled patterns in the definition of the decision boundary between changed and unchanged pixels according to a semisupervised learning algorithm. This algorithm models the full complexity of the change-detection problem, which is only partially represented from the seed pixels included in the pseudotraining set. The values of the classifier parameters are then defined according to a novel unsupervised model-selection technique based on a similarity measure between change-detection maps obtained with different settings. Experimental results obtained on different multispectral remote-sensing images confirm the effectiveness of the proposed approach.

TL;DR: In this article, the results were interpreted assuming progressive evolution of the random coil regions forward the more stable β-sheet conformation, as induced by the different applied preparation conditions or treatment.
Abstract: Films of silk fibroin cast from fibroin-water solutions at different casting temperatures and untreated or treated after casting with methanol, were characterized by differential scanning calorimetry (DSC), under static and dynamic mode, thermogravimetric analysis and dynamic mechanical thermal analysis. DSC revealed the presence of a lower temperature endothermic phenomenon centered at about 70 °C for the as-prepared room temperature cast film, and other typical material thermal parameters - glass transition, crystallization, and thermal degradation - more or less pronounced depending on the specific preparation procedure and thermal or solvent treatment. These results were interpreted assuming progressive evolution of the random coil regions forward the more stable β-sheet conformation, as induced by the different applied preparation conditions or treatment. The low temperature endothermic transition observed in DSC (30-120 °C) corresponded in the dynamic mechanical analysis to a quite anomalous behavior, with a sharp decrease and immediate increase of E'. Conditions producing modifications of the thermal and dynamic mechanical curves, as well as analogies with the thermogravimetric analysis findings, were analyzed and discussed.
