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… Show more

“…During the operation, the data information goes through the operation of each convolutional layer. The calculation performed by the neural network is actually the dot product of the input value vector and the weight matrix of each layer to obtain the final output result [ 17 ]. Backpropagation stage It comes out to define the cost function loss: where x is the number of samples in the sample set, and W is the number of layers of the convolutional neural network.…”

“…In formula (10) and formula (11), Iðx, yÞ represents the gray value at ðx, yÞ; then, the modulus value and direction of the directional gradient at the ðx, yÞ point can be expressed as As shown in Figure 2, this design can better optimize the detector or tracker to a certain extent for the tracking effect and can basically achieve the effect of real-time tracking. The speed can be adjusted according to the scale of Re-ID.…”
