Problems solved by technology

However, its disadvantages are that, on the one hand, this method uses HOG or grayscale to extract the features of the target, which can only extract the rough features of the target, which is easy to cause the problem of tracking delay, which in turn affects the tracking accuracy. The KCF algorithm ignores the factors that the tracked target may be blurred or partially occluded when designing the objective function. When the target is blurred or partially occluded, it is easy to cause target tracking loss, and its tracking accuracy is more limited.
