Image classification by a two dimensional hidden Markov model
- IEEE TRANS. SIGNAL PROCESSING
, 2000
"... For block-based classification, an image is divided into blocks and a feature vector is formed for each block by grouping statistics extracted from the block. Conventional block-based classification algorithms decide the class of a block by examining only the feature vector of this block and ignorin ..."

probability are searched jointly for all the blocks. Applications of the HMM algorithm to document and aerial image segmentation show that the algorithm outperforms CART TM,LVQ, and Bayes VQ.
BIOINFORMATICS CART Variance Stabilization and Regularization for High Throughput Genomic Data
"... Motivation: mRNA expression data obtained from high through-put DNA microarrays exhibit strong departures from homogeneity of variances. Often a complex relationship between mean expres-sion value and variance is seen. Variance stabilization of such data is crucial for many types of statistical anal ..."

analyses, while regulariza-tion of variances (pooling of information) can greatly improve overall accuracy of test statistics. Results: A Classification and Regression Tree (CART) procedure is introduced for variance stabilization as well as regularization. The CART procedure adaptively clusters genes
The Accuracy of Measurements from Medical Images Compressed by Vector Quantization
, 1997
"... This paper has several purposes. One is to describe a particular set of algorithms for clustering and to show how they led to codes which can be used to compress images. The approach is called tree-structured vector quantization and amounts to a binary treestructured two-means clustering, very much ..."

in the spirit of CART TM . Another purpose is to put the coding into the larger framework of information theory. And a third is to report on how the methodology for image compression was applied in a clinical setting where the medical issue was the measurement of major blood vessels in the chest
On Local Orthonormal Bases For Classification And Regression
- Comptes Rendus Acad. Sci. Paris, Serie I
, 1995
"... We describe extensions to the "best-basis" method to select orthonormal bases suitable for signal classification and regression problems from a large collection of orthonormal bases. For classification problems, we select the basis which maximizes relative entropy of time-frequency energy ..."

and Regression Tree (CART TM ). The performance of these statistical methods is enhanced since the proposed methods reduce the dimensionality of the problems without losing important information for the problem at hand by using the basis functions which are welllocalized in the time-frequency plane as feature

OPTICAL AND SAR IMAGERY FOR MAPPING VEGETATION GRADIENTS IN BRAZILIAN SAVANNAS: SYNERGY BETWEEN PIXEL-BASED AND OBJECT-BASED APPROACHES
"... The objectives of this study were (a) to evaluate the suitability of SAR imagery for discriminating savanna physiognomies, (b) to combine SAR and optical imagery for achieving improved accuracy, and (c) to develop a hybrid approach based on pixels and objects to characterize gradients of vegetation ..."

The PALSAR image was acquired in September 5 th 2007, in dual polarization (HH and HV) with an off-nadir viewing angle of 34.3 o. The TM image was acquired
PHYSIOLOGICAL AND METABOLIC RESPONSES TO CONSTANT-LOAD EXERCISE ON AN INCLINED STEPPER AND TREADMILL

This study evaluated oxygen uptake (VO2), heart rate (HR), and lactate [HLa] responses between the treadmill (TM) and the CardiosquatTM 1650 LETM inclined stepper by StairMasterTM (SM) during constant-load exercise. The slow component of VO2 (SC) was a central variable assessed during exercise. Twen ..."
