Abstract
A method for determining a gesture includes determining a change in a background of an image from a plurality of images, determining a object in the image, determining a trajectory of the object through the plurality of images, and classifying a gesture according to the trajectory of the object.
Claims19
A method for automatically remotely issuing commands to a medical imaging workstation comprising the steps of:
- determining a change in a background of an image from a plurality of images;
- determining an object in the image,
- identifying a gesture according to a trajectory motion pattern of the object;
- determining if the motion pattern corresponds to a valid command by classifying the motion pattern along windows in time;
- and
- if the motion pattern corresponds to a valid command, the workstation automatically executing the command resulting in translational and rotational manipulation of a virtual visualization tool based on the command.
The method of 6 wherein repetition of a command increases the intensity of the corresponding command response.
A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method steps for automatically remotely issuing commands to a medical imaging workstation, the method steps comprising:
- determining a change in a background of an image from a plurality of images;
- determining an object in the images;
- identifying a gesture according to a trajectory and motion pattern of the object;
- determining if the motion pattern corresponds to a valid command by classifying the motion pattern along window in time;
- and
- if the motion pattern corresponds to a valid command, the workstation automatically executing the command resulting in translational and rotational manipulation of a virtual visualization tool based on the command.
