摘要:
A method of identifying a product code that has been applied to a product, the method comprising;capturing an image of the product to create a captured image containing the product code and a predetermined reference identifier that is positioned at a predetermined location in relation to the product code;analysing the captured image to identify the reference identifier;using the reference identifier to determine the position of the product code; and analysing a portion of the captured image corresponding to the determined position of the product code to identify the product code.
摘要:
Software may be used to train a person's movements (e.g., in sports, in training, etc.) by displaying a first recording and a real-time video of a user. The first recording may relate to a motion of an ideal subject, where a first set of points are identified on the ideal subject's body throughout the motion. The video of the user may be displayed while playing the first recording, where a second set of points are identified on the user's body throughout the user's motion. An indication may be provided to the user when a position of one or more of the first set of points corresponds with a position of one or more of the second set of points.
摘要:
The present invention relates to a method for determining data referred to as target change data which can be used for performing radiotherapy treatment, the target change data describing information on the change of position of a target included in a body of a patient, the method being performed by a computer and comprising the following steps: • acquiring determination rule data describing a rule for mapping an indicator change set to the target change data, the indicator change set being a set which comprises more than one element, the elements of the indicator change set respectively representing information on respective changes of positions of indicators, at least two of the indicators respectively indicating a change of position of different body structures referred to as indicator structures, • acquiring set data describing an acquired indicator change set; and • determining the target change data based on the determination rule data and the set data by applying the rule for mapping to the acquired indicator change set.
摘要:
A method and system of determining a sub-pixel point position of a marker point in an image. Embodiments of the invention allow a marker point sub-pixel localization module executable by an electronic processing unit to obtain an image, including a marker point, and to derive both a background corrected marker point profile and a background and baseline corrected marker point profile. Additionally, embodiments of the invention allow defining of a sub-pixel position of the marker point as a center of a peak of the background corrected marker point profile. Thus, embodiments of the invention allow for rapidly detecting and localizing external markers placed on a patient in projection images.
