Abstract: Selon l'invention, l'analyse de bande de dimension est utilisée pour déterminer si une région chromosomique présente ou non une aberration de nombre de copies ou une modification épigénétique. De multiples plages de dimensions peuvent être analysées au lieu de se concentrer sur des dimensions spécifiques. Grâce à l'utilisation de multiples plages de dimensions au lieu de dimensions spécifiques, des procédés permettent d'analyser davantage de lectures de séquence et d'être en mesure de déterminer si une région chromosomique présente ou non une aberration de nombre de copies même lorsque l'ADN cliniquement pertinent peut être une petite fraction de l'échantillon biologique. L'utilisation de multiples plages peut permettre l'utilisation de toutes les lectures de séquence provenant d'une région génomique, plutôt qu'un sous-ensemble sélectionné de lectures dans la région génomique. La précision de l'analyse peut être augmentée, la sensibilité étant plus élevée à une spécificité similaire ou supérieure. L'analyse peut comprendre moins de lectures de séquençage pour obtenir la même précision, ce qui permet d'obtenir un procédé plus efficace.

Abstract: Provided are a watermark image OCR method and a system thereof, the method comprising the following steps: correcting coordinates of an image; acquiring a watermark identifier of the image; calibrating corresponding coordinates of an area of the watermark identifier portion; extracting the area including the watermark identifier portion; removing the area including the watermark identifier portion from the image; carrying out greyscale processing on the area including the watermark identifier portion; carrying out USM sharpening processing on the area including the watermark identifier portion; carrying out binarization processing on the area including the watermark identifier portion; combining the area of the watermark identifier portion after binarization processing with an original image according to the coordinates; and executing OCR. In the method, a pattern of a watermark portion is extracted for greyscale processing, sharpening processing and binarization processing, and the pattern is then combined with an original image so as to be uniformly subjected to OCR. Since an image of an area of the watermark portion is merely processed, difficult entire image recognition caused by uniform processing is avoided, and characters of the watermark portion are highlighted, so that the recognition accuracy of the characters of the watermark portion can be effectively improved.
