摘要:

针对传统目标跟踪算法计算复杂度高,在发生遮挡、形状改变时,运动目标丢失的问题,提出了将图像感知哈希算法应用于目标跟踪问题上,并针对行人这一特定目标进行了改进。按照行人的特征,将其分成若干区域,给不同区域分配不同权重,计算跟踪目标的感知哈希值,计算待测区域的哈希值,选择合适的待测区域作为目标区域。该算法与MeanShift算法相比,能更好地处理目标遮挡,不易产生目标丢失,且具有较低的复杂度。

关键词: 感知哈希算法, 目标跟踪, 遮挡, 目标丢失, MeanShift

Abstract:

Traditional target tracking algorithms suffer high computational complexity, occlusion, shape change, and loss of target motion. The image perceptual hash algorithm is used in target tracking and improved for the special target of pedestrians. First pedestrians are divided according to their characteristics into several regions that are assigned different weights. The perceptual hash value of the tracking target is calculated, and the diamond search algorithm is used to calculate the area of the hash value of the unknown. Finally the suitable area is chosen to be tested as the target region. This algorithm has better continuity of target occlusion and tracking than the MeanShift algorithm.

Key words: perceptual hash, target tracking, occlusion, target loss, MeanShift
