Accidental spread of potentially toxic gases, fumes, and particulate chemicals has been reported recently in various cities throughout the country and appears to be on the increase throughout the world in the past few years. Moreover, cerebral trauma

We present new invariance and scaling results for scale space analysis of hyperspectral data. First, we note that a hyperspectral curve can be segmented into independent regions selected by features of scale space fingerprints. These fingerprint feat

Scale space fingerprints provide a natural formalism for modeling terrains because they describe a hierarchy of edges over a broad range of physical scales. The simplest fingerprint descriptor is the feature density function N (σ)—the number of te

A model Hamiltonian for the n = 1 and n = 2 states of the first‐ and second‐row atoms is developed. The model is easily soluble and represents total and ionization energies reasonably well. The model is constructed on a cubic lattice space and is

A new technique utilizing color photography in aerial water analysis is described. The technique termed the scene color standard (SCS) technique, uses natural objects in the photographic image to remove peripheral effects in the water quality measure

Basic technologies for automatic mapping of terrain features from black and white imagery are summarized. The principal effects inhibiting automatic mapping--sensor, film, and atmospheric variables--are accounted for with a set of simple normalizatio

Variations in the relative value of the blue and green reflectances of a lake can be correlated with important optical and biological parameters measured from surface vessels. Measurement of the relative reflectance values from color film imagery req

Photographs of a ground-based laser beacon were taken by astronauts on board the Skylab spacecraft. Unexpected large and elliptical laser-beam images were recorded. The photographic results are presented and discussed in terms of possible atmospheric
