Abstract
(EN) The present invention relates to an apparatus and method for detecting spots within a diagnostic kit result image. The apparatus for detecting spots within a diagnostic kit result image, according to the present invention, comprises: an image acquisition unit that acquires a diagnostic kit test result image via an image scanner of screening equipment; a reference point detection unit that detects a reference point on the acquired diagnostic kit test result image; an image pre-processing unit that extracts a region of interest (ROI) by aligning the diagnostic kit test result image on the basis of the detected reference point; a spot detection unit that detects spots on the extracted region of interest by using an image denoising technique and a blob detection algorithm; a negative/positive reading unit that determines negative or positive by quantitatively numericalizing the degree to which a positive reaction has occurred in the detected spots; and a reading result output unit that displays a value of the determined result.
(FR) La présente invention concerne un appareil et un procédé de détection de zones dans une image de résultat de kit de diagnostic. L'appareil pour détecter des zones dans une image de résultat de kit de diagnostic, selon la présente invention, comprend : une unité d'acquisition d'image qui acquiert une image de résultat de test de kit de diagnostic par l'intermédiaire d'un dispositif d'analyse d'image d'un équipement de dépistage ; une unité de détection de point de référence qui détecte un point de référence sur l'image de résultat de test de kit de diagnostic acquise ; une unité de prétraitement d'image qui extrait une région d'intérêt (ROI) en alignant l'image de résultat de test de kit de diagnostic sur la base du point de référence détecté ; une unité de détection de zone qui détecte des zones sur la région d'intérêt extraite à l'aide d'une technique de débruitage d'image et d'un algorithme de détection de blob ; une unité de lecture négative/positive qui détermine un négatif ou un positif en numérisant quantitativement le degré auquel une réaction positive s'est produite dans les zones détectées ; et une unité de sortie de résultat de lecture qui affiche une valeur du résultat déterminé.
