中文说明：基于核相关滤波器的跟踪算法，将HOG特征与颜色特征相融合，并加入了尺度变化，使得目标在发生尺度变化、遮挡和背景干扰等情况下，能够有效的跟踪目标。
English Description：
The tracking algorithm based on kernel correlation filter combines hog feature with color feature, and adds scale change to make the target track effectively in the case of scale change, occlusion and background interference.
