Method and apparatus for tracking image patch considering scale |
摘要 |
A method and apparatus for tracking an image considering scale are provided. A registered image patch may be divided into a scale-invariant image patch and a scale-variant image patch according to a predetermined scale invariance index (SII). If a registered image patch within an image is a scale-invariant image patch, the scale-invariant image patch is tracked by adjusting its position, while if the registered image patch is a scale-variant image patch, the scale-invariant image patch is tracked by adjusting its position and scale. |

1. An image patch tracker, including one or more processing devices, the image patch tracker comprising:
a scale invariance index (SII) calculating unit including at least one of the one or more processing devices to calculate an SII based on a pixel value change with respect to a scale change for a registered image patch; and a scale characteristic deciding unit including at least one of the one or more processing devices to compare the SII to a threshold and to selectively determine the registered image patch to be one of a scale-invariant image patch, when the SII is less than the threshold, and a scale-variant image patch, when the SII is not less than the threshold. |
