چکیده

Localized discriminant analysis methods are introduced for image classification in order to take account of spatial correlation present in data arising in several applications. Comparisons are made with the ICM method. Numerical experiments on synthetic datasets are worked out. The methods are applied to the retrieval of the cloud mask from satellite remote sensed images. Riassunto: Vengono introdotti metodi localizzati di analisi discriminante per la classificazione di immagini allo scopo di tenere conto della correlazione spaziale presente nei dati che originano da numerose applicazioni. Vengono effettuati confronti con il metodo ICM. Sono presentati esperimenti numerici su dataset sintetici. I metodi sono poi applicati alla ricostruzione del campo di nuvole a partire da immagini telerilevate da satellite.

Variable selection in model-based discriminant analysis

A general methodology for selecting predictors for Gaussian generative classification models is presented. The problem is regarded as a model selection problem. Three different roles for each possible predictor are considered: a variable can be a relevant classification predictor or not, and the irrelevant classification variables can be linearly dependent on a part of the relevant predictors o...

Determination of the Species from Skeletal Remains Through Histomorphometric Evaluation and Discriminant Analysis Determinación de la Especie a Partir de Restos Óseos Mediante Evaluación Histomorfométrica y Análisis Discriminante

In situations where the skeletal remains found are too fragmented, it is necessary to assess the human origin of such remains; for this purpose, various parameters are used, both anatomical and histological. The objective of the present study is to evaluate the various histomorphometric parameters to differentiate human from non-human bones, to further construct discriminatory functions that al...

New Adaptive Linear Discriminante Analysis for Face Recognition with SVM

We have applied new accelerated algorithm for linear discriminate analysis (LDA) in face recognition with support vector machine. The new algorithm has the advantage of optimal selection of the step size. The gradient descent method and new algorithm has been implemented in software and evaluated on the Yale face database B. The eigenfaces of these approaches have been used to training a KNN. R...
