Two basic models of functioning of agricultural economics, which differ in their main objectives. „Closed” system has as its objective the support of family farming, which provide production factors and opportunities for the entry of new producers are heavily restricted. „Open“ system is based on the concept that agricultural land is not only one of the acceptable forms of investment, but also a source of income for the farm family.
The banks cannot or should not at least grant long-term loans for investment, since their resources are raised from deposits and investments, most of which can be downloaded at any time or in negotiated shortly. This is necessary to seek other sources of funds that can be used for investment purposes necessary long-term capital. Such a source in the market economy is the issue, purchase respectively sale of certain securities in the capital market in order to provide the necessary investment funds.
In the present report a method is presented for automated data processing of color digital images of yellow cheese by identifying areas contaminated with mold on the surface of the product. Selected are functions suitable for data analysis. Defined are color features suitable for separating the areas with yellow cheese and mold. Used are binarization and analysis of histograms of the images. Defined is range between 3,1÷3,5 for correction factor of binarization threshold where in the recognition of object area with mold is obtained total error of 5%.
The report is a study on application of image processing techniques to SEM digital images in the evaluation of quality of the thermally processed and magnetically threated ceramic materials. In evaluation of the images by histograms a significant difference in intensity is observed in the images of ceramics treated with varying strength of the magnetic field but have not obtained good results in images of ceramics processed at different temperatures. Analogous results were obtained using discriminant analysis by feature „orientation”. The application of texture features indicate visually that there are significant differences in the data for features contrast and energy, which is a prerequisite for the realization of further research on rapid and objective assessment of magnetically treated ceramics.
The report gives an overview of existing technologies used in modern interactive presentation systems listed are their advantages and disadvantages. Mentioned are additional devices to the interactive presentation systems incorporating interactive whiteboards and in particular the document cameras and their technical capabilities and shortcomings. Choice of foodstuff is made and the surface characteristics that will be recognized. Presented is the process used to separate the object from the background in image. The results mentioned are by removing object areas by binarization of the image in color features and by presenting the full spectrum of the image. Classification by three classifiers using linear separating functions. Determined is the total error of classification and time for data processing. Referred are the opportunities for the application of investigation system for receiving and processing images in school activities.
