This paper describes a procedure for a multitemporal interpretation of vegetation areas in Brazil using Landsat TM images. We started with a monotemporal interpretation of the first epoch of the scene by using both spectral and structural features. For interpretation of temporal changes we discretely described temporal conditions of regions, and transferred(More)

The problem of detecting specific patterns in images of materials obtained through High Resolution Transmission Electron Microscopy is addressed. A supervised classification method is proposed using an extension of Principal Component Analysis and a new a procedure for building the training set. Experiments on two different types of images indicate that the(More)
The idea behind the E-FOTO project is to offer a simple set of software and didactic material that could help students understand the principles behind Photogrammetry. The project is based upon two main principles: freedom of use and self-teaching, so, the students can fully understand the principles behind Photogrammetry – reading the e-book, using the(More)
This work proposes a framework for increasing the degree of automation of low-resolution satellite images interpretation procedures. Basically, the method starts with an image segmentation which, according to a criterion of spectral response homogeneity, outlines the regions to be classified. The classification procedure is aided by expert knowledge. This(More)
This study aims to automatically determine changes in urban areas from multi-temporal, multi-scale, and multi-platform remotely sensed data as a base for estimating changes in population. The data sets used were a stereo pair of IKONOS panchromatic images and three stereo pairs of digitized airborne images taken at different epochs. The study is carried out(More)
