Summary: Research on the project: "Systems and Aghoritms in Measurement and Signal Processing" in the period 1994-95 can be divided in 5 groups: 1. Digital Signal Processing. In the area of DSP, following was developed: a) Novel methods for accuracy enhacement of the digital harmonical analysis. b) An image receiving system from meteorological satelites was realized. c) A novel approach for the antialiasing filter optimization was suggested. d) Wavelet transform were studied for the purpose of application in the DSP. 2. Digital Image Processing. a) A method for shape description by means of the morphological signature transform was applied to the problem of 3-D CT image registration. b) Procedures were developed for the intelligent biomedical image analysis. c) New methods for morphological shape analysis are developed. d) Algorithms for fast object labeling and fast contur extraction from gray scale images were developed and implemented. 3. Measurement Systems. a) A special purpose measurement system controlled by PC was developed. Software for mesurement, signal analysis, diagnostics and setting of measurement parameters was developed, too. b) A new robust distance measurement method was proposed. 4. Information Networks. a) A study of development of the Croatian academic information networks was done, as a part of the CARNet project. A number of testing based on ATM and other network equipment were done, for the purpose of further development of the network. 5. Analog Sygnal Processing. a) Biquartic band-pass active filter blocks based on the realization using Sallen & Key second-order sections were studied.

Keywords: digital signal processing, digital image processing, measurement systems, information networks, analog signal processing

Research goals: 1. Digital Signal Processing a) The research goal was to develop more accurate methods for the harmonic signal analysis. b) Solve neccessary processing for the receiving of meteorological satelite images. c) Find optimal antialiasing filters based on constraints on time and frequency response. d) Study the Wavelet transform for the purpose of multiresolution signal analysis. 2. Digital Image Processing a) The research goal was to develop new methods for the shape analysis based on mathematical morphology. b) Develop procedures for intelligent biomedical image processing and analysis based on the use of clustering methods and neural networks. c) Develop algorithms for 2-D and 3-D shape representation using multiresolution morphological image processing. d) Develop and implement algorithms for object extraction faster than already known. 3. Measurement Systems a) Develop a special purpose measurement system controlled by a PC. b) Propose a robust distance mesurement method. 4. Information networks. a) The research goal was to choose optimal information network technologies and equipment for further development of the CARNet. 5. Analog Sygnal Processing. a) The research goal was to investigate the sensitivity of the biquartic band pass filters realized by two operational amplifiers using Sallen & Key second order sections.
