Title (EN) METHOD FOR PICKING UP AND REPRESENTING THERMOGRAPHIC IMAGES
(FR) PROCEDE DE SAISIE ET REPRESENTATION D"IMAGES THERMOGRAPHIQUES
Abstract: front page image
(EN)The method for picking up and representing thermographic images of biological or technical structures, allows the sensing of abnormal temperature repartitions even when they are very low or when the corresponding areas differ very slightly as to their temperature values with respect to adjacent temperature values. According to this method, the temperature values for each image point of a thermogram are digitally picked up and recorded and the pitch of the local temperature variation is calculated, that is to say the temperature gradient for each image point in relation to its temperature and to the temperature value measured for the point adjacent thereto. For a selected image area, the local repartition of temperature gradients is represented. Abnormal temperature repartitions may thus by sensed, from such representation, where important temperature gradients exist.
(FR)Le procede de saisie et representation d"images thermographiques de structures biologiques ou techniques, permet de reconnaitre des repartitions anormales de temperature aussi lorsque celles-ci sont tres faibles ou lorsque les zones correspondantes se differencient tres faiblement en ce qui concerne leur valeur de temperature par rapport aux valeurs de temperature adjacentes. Selon ce procede, on saisit les valeurs de temperature de chaque point d"image d"un thermogramme de maniere numerique et on calcule la pente de la variation locale de temperature, c"est-a-dire le gradient de temperature pour chaque point d"image en fonction de sa temperature et de la valeur de temperature mesuree du point qui lui est adjacent. Pour une zone de l"image choisie, on represente la repartition locale des gradients de temperature. Des repartitions anormales de temperature peuvent ainsi etre reconnues, a partir de cette representation, la ou se presentent des gradients de temperature importants.
