    • A method of automatically detecting and tracking successive frames in a region of interesting by an electronic imaging device includes: decomposing a frame into intensity, color and direction features according to human perceptions; filtering an input image by a Gaussian pyramid to obtain levels of pyramid representations by down sampling; calculating the features of pyramid representations; using a linear center-surround operator similar to a biological perception to expedite the calculation of a mean value of the peripheral region; using the difference of each feature between a small central region and the peripheral region as a measured value; overlaying the pyramid feature maps to obtain a conspicuity map and unify the conspicuity maps of the three features; obtaining a saliency map of the frames by linear combination; and using the saliency map for a segmentation to mark an interesting region of a frame in the large region of the conspicuity maps.
    • 一种通过电子成像装置自动检测和跟踪感兴趣区域中的连续帧的方法包括:根据人的感知将帧分解为强度,颜色和方向特征; 通过高斯金字塔过滤输入图像,通过下采样获得金字塔表示的水平; 计算金字塔表示的特征; 使用类似于生物学感知的线性中心环绕算子来加速计算周边区域的平均值; 使用小中心区域和周边区域之间的每个特征的差作为测量值; 叠加金字塔特征图获得显眼图,统一三个特征的显眼图; 通过线性组合获得帧的显着图; 并使用显着性图进行分割,以标识显眼图中较大区域中的一个有趣区域。
