# ABSTRACT

## Introduction

This paper research an improved biological image tracking algorithm of athlete’s cervical spine health under color feedback.

## Objective

A new algorithm is proposed to improve the accuracy of detection and tracking.

## Methods

In this study, the first thing is to apply the color feedback algorithm to improve and optimize the Improved Camshift algorithm. The optimized algorithm was used to track the center of the image, and the video was processed frame by frame. The center position of the tracking frame was obtained.

## Results

The average number of head twists per person is 39 times. Among the three groups, children twisted the least, and older adults twisted the most.

## Conclusion

The algorithm proposed in this study has certain effectiveness and superiority and can be well applied to detecting the number of head twists during exercise. Level of evidence II; Therapeutic studies - investigation of treatment results.
