Title (EN) METHOD AND APPARATUS FOR INFRARED THERMAL IMAGE CONTOUR EXTRACTION
(FR) PROCÉDÉ ET APPAREIL D'EXTRACTION DE CONTOUR D'IMAGE THERMIQUE INFRAROUGE
Abstract:
(EN) The present disclosure provides a method and apparatus for infrared thermal image contour extraction. The method includes: obtaining an infrared thermal image; and determining histograms based on grayscale image of the infrared thermal image, determining segmentation thresholds of the infrared image based on the histograms, and extracting a contour based on the segmentation thresholds. The apparatus includes an image acquisition circuit, configured to capture an infrared thermal image; and a processing circuit, configured to determine histograms based on greyscale images of the infrared thermal image, to determine segmentation thresholds of the infrared thermal image based on the histograms, and to extract a contour based on segmentation thresholds.
(FR) La présente invention concerne un procédé et un appareil d'extraction de contour d'image thermique infrarouge. Le procédé consiste à : obtenir une image thermique infrarouge; et déterminer des histogrammes en se basant sur une image en niveaux de gris de l'image thermique infrarouge, déterminer des seuils de segmentation de l'image infrarouge sur la base des histogrammes, et extraire un contour sur la base des seuils de segmentation. L'appareil comprend un circuit d'acquisition d'image, conçu pour capturer une image thermique infrarouge; et un circuit de traitement, conçu pour déterminer des histogrammes en se basant sur les images en niveaux de gris de l'image thermique infrarouge, pour déterminer des seuils de segmentation de l'image thermique infrarouge sur la base des histogrammes, et pour extraire un contour sur la base des seuils de segmentation.
