摘要:
way acquisition characteristics individual especially to systems for biometric using matrices of focusing elements or diffuser light and camera matrices on the basis of veins and arteries vascular limbs using the difference in absorption of radiation i keep has spektroskopowego by hemoglobin and other tissues of the organism,taking into account the approach multibiometryczne one or many individual characteristics with acquisitions is that in the first stage, this stage is the acquisition, performs at least one image of the vascular system, biometric favourably veins and arteries, understood as a different ca absorption spectrum radiation by hemoglobin and other tissues of the organism,the test object through the lighting object favourably by matrix diodes and registration using matrix camera with filters, after which in a second stage, obtained images are evaluated qualitatively by one or multiple procedure advantageously using functions kryterialne assessing the quality of each of the received images.if the quality of image by the determined qualitative assessment and \/ or by functions kryterialne is above threshold value image is transmitted for further analysis in a biometric system while, if the quality of the image determined by the functions kryterialne is below \u017cej threshold valueit implements the change of wavelength diode matrix elements in a sequential manner and \/ or the overall operations of the first stage and shall be repeated for new line parametersat all stages is repeated automatically creating a feedback mechanism advantageously repeatedly to transition time qualitative evaluation by exceeding the threshold value by any of the images.the decision-making system acquisition characteristics individual especially to systems for using biometric repository is characterized by the fact that contains interconnected and cooperating with each other elements which constitute the individual characteristics of the individual acquisition unit (1) connecte
