METHOD FOR AUTOMATICALLY PROCESSING A DIGITAL SIGNAL OF THE TYPE COMPRISING A SUCCESSION OF PHASES WITH REPRESENTATIVE VARYING PHASES OF THE STUDY PHENOMENON AND RAPID VARIATION PHASES, AND DEVICE FOR IMPLEMENTING THE SAME

摘要

The present invention relates to a method for the automatic processing of a digitized signal of the type comprising an inheritance of slow-changing phases representative of the studied phenomenon, and fast-changing phases consisting in rejecting said fast phases and in extracting the phase phases. SLOW VARIATIONS, AND ACHIEVING AT LEAST THE FOLLOWING STEPS: - THIS SIGNAL IS SAMPLE AND DIGITALIZED, THE SAMPLING FREQUENCY BEING SUPERIOR TO THE FREQUENCY OF SHANNON, - THE DIGITAL SIGNAL IS DERIVED BY A DERIVATOR DIGITAL FILTER, - A FUNCTION OF GLOBAL MEMBERSHIP OF EACH SLOW PHASE SAMPLE VALUE IS CONSTRUCTED DURING THE FIRST SCAN OF THE SAMPLE DIGITAL SIGNAL DERIVED, - THE OVERALL FORM OF THE SIGNAL IS DETECTED BY ADJUSTING THE CURVE ON THE SIGNAL DERIVED WITH THE CRITERION OF LESS SQUARES, - A FUNCTION OF FINE MEMBERSHIP OF SAMPLE VALUES AT THE SLOW PHASE IS CONSTRUCTED DURING A DEU XI SCANNING, / P P - THE SAMPLE VALUES ARE CLASSIFIED ACCORDING TO THEIR MEMBERSHIP TO SLOW PHASES OR RAPID PHASES, - THE RAPID PHASES ARE ELIMINATED, - A SIGNAL CUMULATED FROM SLOW PHASES IS BUILT. / P P The present invention relates in particular to the processing of images, the processing of NYSTAGMIC SIGNALS or the automatic classification. The present invention also relates to a device for carrying out this process. / P
