Insufficient Knowledge

Most modern systems and technologies of the automated analysis of medical microscopic images and early diagnostics of oncological diseases are analyzed in the article. The methods and algorithms used for image processing, segmentation, determination of parameters of the object, which are determined manually and require additional knowledge, make it significantly complicated for their practical application in clinical medicine due to insufficient knowledge of medical staff.

Determination Of Parameters

The article deals with determination of parameters for leakage of hazardous substances by using of computer programs ALOHA and EFFECTS PLUS. The calculated parameters are compared in a practical application for gas tanks with regard to limitation of these programs. There are compared the possibilities of using of this programs, particularly for determining the parameters of a very small leak to determine exactly areas with the potentially explosive atmospheres. In conclusion of the study are summarized the possibilities of using and the proposals of computer programs in case of leakage of propane from the tank.

Ill Posed

Despite the skill and determination of electro-optical system designers, the images acquired using their best designs often suffer from blur and noise. The aim of an “image enhancer” such as myself is to improve these poor images, usually by digital means, such that they better resemble the true, “optical object,” input to the system. This problem is notoriously “ill-posed,” i.e. any direct approach at inversion of the image data suffers strongly from the presence of even a small amount of noise in the data. In fact, the fluctuations engendered in neighboring output values tend to be strongly negative-correlated, so that the output spatially oscillates up and down, with large amplitude, about the true object. What can be done about this situation? As we shall see, various concepts taken from statistical communication theory have proven to be of real use in attacking this problem. We offer below a brief summary of these concepts.

For many years the concept of quantitative diffraction contrast experiments might have consisted of the determination of dislocation Burgers vectors using a g.b = 0 criterion from several different 2-beam images. Since the advent of the personal computer revolution, the available computing power for performing image-processing and image-simulation calculations is enormous and ubiquitous. Several programs now exist to perform simulations of diffraction contrast images using various approximations. The most common approximations are the use of only 2-beams or a single systematic row to calculate the image contrast, or calculating the image using a column approximation. The increasing amount of literature showing comparisons of experimental and simulated images shows that it is possible to obtain very close agreement between the two images; although the choice of parameters used, and the assumptions made, in performing the calculation must be properly dealt with. The simulation of the images of defects in materials has, in many cases, therefore become a tractable problem.
