基于纹理颜色模型的高原鼠兔突变运动跟踪
针对自然生境环境下高原鼠兔跟踪中,鼠兔毛色呈保护色与背景颜色相近以及运动随机的问题,构造了一种局部纹理差异性算子LTDC(local ternary difference count),来表征目标和背景之间的细微差异性,弥补了采用单一LTC(local ternary count)算子的不足。通过运动信息来判断鼠兔的运动模式,不同的模式采用不同的采样跟踪策略。把所构造的LTDC算子与R(red)G(green)B(blue)颜色信息相结合来表示目标,并把该目标表示模型引入到运动信息引导的高原鼠兔跟踪方法中。通过对采集的秋冬季节高原鼠兔视频图像进行测试,分析跟踪的成功率和误差,得到的LTDC纹理...

| Summary: | 针对自然生境环境下高原鼠兔跟踪中,鼠兔毛色呈保护色与背景颜色相近以及运动随机的问题,构造了一种局部纹理差异性算子LTDC(local ternary difference count),来表征目标和背景之间的细微差异性,弥补了采用单一LTC(local ternary count)算子的不足。通过运动信息来判断鼠兔的运动模式,不同的模式采用不同的采样跟踪策略。把所构造的LTDC算子与R(red)G(green)B(blue)颜色信息相结合来表示目标,并把该目标表示模型引入到运动信息引导的高原鼠兔跟踪方法中。通过对采集的秋冬季节高原鼠兔视频图像进行测试,分析跟踪的成功率和误差,得到的LTDC纹理颜色模型的目标表示方法在鼠兔发生突变运动时,由于采用了运动信息引导的采样跟踪方式,能够有效地捕获突变目标,跟踪成功率达到97.93%。在鼠兔发生平滑运动时,尽管目标与背景颜色相近,依然能够稳定地跟踪目标,跟踪误差较小,误差波动范围也较小,误差均值为19.56,误差方差为74.24。试验结果表明:所提出的跟踪方法具有较强的目标与背景区分能力,在目标和背景颜色相近、运动复杂的场景中,能够较为准确地实现高原鼠兔目标的定位。 |

Video-based animal behavior analysis is a critical and fascinating problem for both biologists and computer vision scientists. According to the color similarity between Plateau pika and the background, as well as the uncertainty and randomness of plateau pika motion in natural habitat environment, a new visual descriptor named the local texture difference operator LTDC was proposed to reflect the subtle differences between the plateau pika and the background. The LTDC operator, being more robust to target expres |
