First Claim
Patent Images
1. A method of processing video image data, the method comprising the steps of:
- generating, based on the video image data, a plurality of silhouettes of a figure represented in the video image data;
forming a plurality of matrices, each matrix representing a silhouette in a frame of the video image data;
establishing a motion portrait from the plurality of matrices and based on the plurality of silhouettes; and
calculating motion characteristics from the plurality of matrices and based on the plurality of silhouettes, wherein the motion characteristics are used to medically diagnose the figure represented in the video image data.

Abstract
Video image data is received in the form of a sequence of images representative of a subject performing one or more predetermined tasks within a new environment (FIG. 3 element 31). A plurality of silhouettes is generated from the video image data and combined to provide a motion portrait (FIG. 6). Motion characteristics are then calculated based on the motion portrait and may be compared with normal or previous motion characteristics as part of diagnostic analysis (38).

2. A method of measuring physiological characteristics of an individual with respect to movement of said individual comprising, in combination, the steps of:
-
video recording the individual performing a predefined routine of physical tasks;
processing, without human intervention, the video image recorded to define a silhouette pattern of the individual movement;
comparing the silhouette pattern with a standard;
determining the deviation of the silhouette pattern from the standard and determining whether at least one physiological characteristic is outside an expected normal range. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 20, 22, 25)

14. A method for performing medical diagnosis based on physical motion of an individual conducted pursuant to a pre-defined protocol, comprising, in combination, the steps of:
-
positioning the individual in a field;
causing the individual to move in accord with an instruction;
video recording the individual movement from a fixed position;
processing, without human intervention, the video image of the individual to highlight the silhouette of the individual; and
in response to the step of analyzing, determining whether the individual movement is associated with an expected normal range.analyzing the modification of the video image by comparing the modification to a standard and in response to the step of analyzing, determining whether the individual movement is associated with an expected normal range. - View Dependent Claims (15, 16, 17, 18, 19, 21, 23)
