How to extract gait parameters of walking pattern from images

Hello,

i have multiple images of persons in which i want to extract some of gait parameters like

Cadence

step length

stride length

step time

gait cycle

But till now i have extracted 3D keypoints from those images

so if anyone have idea how to extract those parameters please help out

The question is not clear. "Mutliple images" can mean nearly everything. But instead of only these images, you explain, that you have "3D keypoints". This sounds much more useful. Please elaborate this: What do you have exactly? Do you have some time information in addition? Otherwise "step time" and "cadence" are impossible to obtain. So please post exactly, which inputs you have and what the problem is.

Hello,

has of now,

I have taken images of single person and given to openpose and got 2D keypoints i have used alogothim then i converted to 3D.

But now i want to extract gait parameters in above statement

***images contain walking pattern of persons

This is still not clear enough to answer your question. What exactly are the available inputs? Which type, which size, which variables, which meaning? Based on the information "converted to 3D" it is impossible to suggest a method to obtain the cadence. You did not mention, how or if the temporal information is stored.

Hello,

i will tell you detailed

I have images of people walking and then i have given to openpose from this i got 2d skeletion data so from this keypoints.

can i get any of the gait parameters from this skeletion values.

There's rich literature (<-link) on extracting gait patterns from biological motion. You might get some suggestions here but why not turn to the primary literature on this topic? There are hundreds (thousands?) of published papers on this.

@Suhas Goravale Siddaramu: You cannot expect the readers to know "openpose". My question was: What exactly are the available inputs. Then it is better to post the definition of the structure of the data than to mention any software you have used to create it. I will not download and install this software only to guess, what you have done with it.

I've worked in the field of motion analysis for 20 years, but this does not allow me to guess the details of your problem.
