Claims23
A computer-implemented method for evaluating a joint of an individual, the method comprising:
- (a) inputting a video of the individual comprising a plurality of frames into a software module, wherein the software module comprises Monte Carlo sampling;
- (b) identifying the joint of the individual within the video with the software module;
- (c) locating the joint at one or more times in the video with the software module, wherein locating the joint comprises using the Monte Carlo sampling to generate sample locations of the joint, wherein the Monte Carlo sampling comprises
- (i) generating draws from a probability distribution characterizing the joint, wherein the probability distribution is parameterized by at least a frame of the plurality of frames;
- and
- (ii) calculating one or more expectation values characterizing the joint from the draws from the probability distribution;
- (d) measuring an angle of the joint at one or more times in the video with the software module;
- and
- (e) assessing the joint based on the measurement of the previous step.

A computer-based system for evaluating a joint of an individual, the system comprising:
- (a) a processor;
- (b) a non-transitory computer-readable medium comprising a computer program configured to direct the processor to:
- (i) input a video of the individual comprising a plurality of frames into a software module, wherein the software module comprises Monte Carlo sampling;
- (ii) identify the joint of the individual within the video with the software module;
- (iii) locate the joint at one or more times in the video with the software module, wherein the Monte Carlo sampling is used to locate the joint by generating sample locations of the joint, wherein the Monte Carlo sampling comprises
- (1) generating draws from a probability distribution characterizing the joint, wherein the probability distribution is parameterized by at least a frame of the plurality of frames;
- and
- (2) calculating one or more expectation values characterizing the joint from the draws from the probability distribution;
- and
- (iv) measure an angle of the joint at one or more times in the video with the software module.
