Title
(EN) MEASUREMENT OF A BLOB PERIMETER OF A DIGITAL IMAGE THAT MAY BE SUBJECT TO DEFECTS
(FR) MESURE DU NOYAU DE FLOU D'UNE IMAGE NUMERIQUE POUVANT ETRE SUJETTE A DES DEFAUTS.
Abstract
(EN)
The method of this invention comprises, on the one hand, the determination of the parameters of the blob perimeter which consists in identifying the real changes in an irregular-shaped albedo, and on the other hand, the processing of possible unblurring of the image based on the principle that these real changes are maybe the irregular shaped images of the moving profile of the object, so that the real transitions are transformed into their corresponding moving profiles. This method is applicable to digital images which may be subject to unfocusing or focusing defects.
(FR)
Le procédé selon l'invention comprend, d'une part, la détermination des paramètres du noyau de flou de l'image consistant à identifier les transitions réelles d'albédo déformées et, d'autre part, le traitement de défloutage éventuel de l'image en partant du principe que ces transitions réelles constituent potentiellement des images déformées de profils de marche de l'objet et en transformant des transitions réelles en profils de marche correspondants. Ce procédé s'applique à des images numériques pouvant être sujettes à des défauts de défocalisation ou de mise au point.
