    摘要: A method and a computer system for preflighting a graphics artwork file. The method includes storing rules corresponding to an object, a set of recognition inputs for identifying the object, and a graphics artwork file to be preflighted. An image is rendered from the graphics artwork file and machine vision identifies a representation of the object in the rendered image, a characteristic of the object, and a value for the characteristic. The identified characteristic value is checked against corresponding values embodied in the rules, and an output of the checking step is provided. The system comprises at least one computer processor, an input, an output, and a plurality of computer memory modules for storing the rules, the recognition inputs, the artwork file, and instructions for performing the rendering, the machine vision, and the checking method.

    摘要: A method for estimating extracorporeal blood volume in at least a portion of a fluid canister. A light source may be activated, and an image of the fluid canister is captured with an optical sensor. The image may be a color frame of a video stream. A color-related feature is extracted from at least a portion of the image. A concentration of hemoglobin is estimated based on the extracted color-related feature. A fluid level of fluid within the fluid canister may be estimated from the image. Extracorporeal blood volume based on the estimated concentration of hemoglobin and a fluid volume or the estimated fluid level. The estimated extracorporeal blood volume is displayed on a display. The estimated extracorporeal blood volume and the estimated fluid level may be monitored over time. The optical sensor may be disposed on a handheld mobile device mounted to a side of the fluid canister.
