摘要:

AbstractWe describe dynamic programming algorithms that are derived on the basis of symmatrized probabilistic models of the terrain and stereo pair and reconstruct the digital terrain model from the ideal horizontal stereo pair as a bunch of planar epipolar profiles. The algorithms show good performance under nonuniform intensity distortions over both images in the stereo pair and can be used both for the long‐range and close‐range computer binocular stereo vision. Experimental results for some real stereo images of the Earth's surface are presen

摘要:

AbstractThe shape from shading procedure is not the only way to interpret the grey‐scale image of a surface independently on illumination conditions. An alternative approach is reported that considers a new surface as an unknown combination of fragments of know shapes, those shapes offering certain invariances to the illumination changeabilit

摘要:

AbstractThe advantage of the new human visual system model consists in its ability to take visual system properties into account more accurately. Because of this, it guarantees close agreement between subjective image impairment assessment on the one hand, and estimations obtained by this model on the other. This fact gives good grounds to exclude the human observer of the iteration process of parameters optimization for television equipment to be developed.

摘要:

AbstractSeveral methods of generalized image quantization, being an ϵ‐network reduction with the use of visual perception limits, are discussed. The corresponding digital image transformations provide an effective image coding with the following image transmission through communication channels and its storage in the databa

摘要:

AbstractWe propose and discuss discrete recurrent algorithms for the retrieval of coherent light fields phase from measurement data of the intensity distribution of their spatial spectra. It is shown that the amplitude‐only and the phase‐only light fields are retrieved uniquely from the modules of their Fourier spectrum while, introducing in that fields the phase and amplitude masks respectively, satisfying certain conditions. Arbitrary amplitude‐phase light fields are retrieved from two modules measurements of their Fourier spectrum, namely, before and after introducing the amplitude‐phas

摘要:

AbstractWe give a brief description of the operation principles of LeaVis, a prototype industrial machine vision system aimed at processing and segmentation of the images of hides marked by lines and other symbols that show defects and areas of different quality. The goal of LeaVis is to provide a visual input for a CAD system that sets trajectories for the knife cutting the hides. We discuss the basic motivations of the vision system design, present some of its algorithms, and demonstrate examples of their operation.

摘要:

AbstractA software system (MicroSegams) is described which is able to acquire, store, present, and process nuclear medicine images. The most important basic procedures (e.g., image acquisition from a gamma camera, selection of a study from the catalogue, drawing regions of interest, etc.) and complete clinical procedures (e.g., renography, brain perfusion, etc.) can be activated directly from the system menu by mouse. The language sLan (a subset of programming languageCcontaining more than 200 elementary functions) can also be used to write new procedures to be interpreted or compiled. The system is offered as a basic tool for the performance of static, dynamic, gated, or tomographic investigations in clinical practice.
