At the light microscope level of resolution several chemicals have been shown to cause "fogging" of photographic film. Among these the principal reducing agents are glutathione, cysteine (1), hydrogen sulfide gas, and hydroquinone in animal tissue (17) . The -SH groups of the first three chemicals were shown to be responsible for the effect . Chemographic reactions of any kind at the electron m...

This paper explores techniques for constructing a 3D computer model of an object from the real world by applying tomographic methods to a sequence of photographic images. While some existing methods can better handle occlusion and concavities, the techniques proposed here have the advantageous capability of generating very high-resolution models with attractive speed and simplicity. The applica...

The application of the speckle phenomenon to the analysis of in-plane translations and oscillations is first reviewed briefly. Then a practical method of investigating out-of-plane rotations (tilts) even in the presence of in-plane movements is studied. This goal can be achieved by recording the speckle patterns in the Fourier transform plane before and after the tilt or as a time-average expos...

This article presents a review of the literature and an evaluation on the development and application of skull-image superimposition technology - both instrumentation and methodology - contributed by a number of scholars since 1935. Along with a comparison of the methodologies involved in the two superimposition techniques - photographic and video - the author characterized the techniques in ac...

This work constitutes a contribution to the emergence of a common writing for French Sign Language in a graphical or even a typographical framework. Our hypothesis is as follows: in its execution, the gestural sign contains a readable graphic trace that can be visualized with a photographic device. In order to evaluate this hypothesis, we gather a photographic corpus made of isolated elicited s...
