Abstract: A browser can include a script monitoring module to monitor executing scripts and log the initiating scripts for API calls or other monitored actions. In some embodiments, the script monitoring module overwrites built-in or web APIs in the browser with versions of the APIs that allow the script monitoring module to identify the scripts calling the APIs. Using the script monitoring module, the script initiating an action (such as an API call) can be identified using features of the browser. In some embodiments, all actions may be monitored in this way, permitting the tracking and analysis of scripts and full analysis of interaction between such scripts on the webpage and with the browser.

Abstract: Intrinsic and extrinsic calibration parameters are determined in real time for a camera positioned to capture images of a surgical site in a body cavity. The camera is positioned on a manipulator arm and used to capture a plurality of frames of images of the surgical site using the at least one camera while moving the camera within the body cavity. 3D position information corresponding to positions of the camera is recorded during capture of said images. A plurality of features between two or more frames of the captured images are matched, and a 3D structure of the plurality of features is reconstructed using multi-frame triangulation. A penalty measure is estimated using a reprojection error. The distance in the image plane between the projected 3D feature and the measurement. Intrinsic calibration parameters are estimated for the at least one camera, and refined to minimize the penalty measure.
