    • A method for identifying features in digital images. The method includes, providing a digital image of a plurality of pixels having one or more features to be identified; providing a feature model having one or more parameters characteristic of a feature to be identified, wherein the feature model has a centroid; and distributing a plurality of test Regions of Interest (ROIs) over the digital image, so that every pixel of the digital image is covered by one or more test ROIs, wherein each test ROI has the same parameter(s) as the feature model, including its centroid. The method then includes for each test ROI, calculating the intensity moment of the image region bounded by the test ROI and if the centroid of the test ROI is offset from the intensity moment, moving the test ROI closer to the intensity moment and reiterating these steps until the centroid and intensity moment have substantially converged, and then processing the next test ROI; determining which ROIs are candidate ROIs; removing duplicate ROIs where two or more candidate ROIs identify the same feature; and outputting the list of candidate ROIs, the positions of which identify the features of interest in the provided image.
    • 一种用于识别数字图像中的特征的方法。 该方法包括:提供具有一个或多个要识别的特征的多个像素的数字图像; 提供具有要识别的特征的一个或多个参数特征的特征模型,其中所述特征模型具有质心; 并且在数字图像上分布多个测试感兴趣区域(ROI),使得数字图像的每个像素被一个或多个测试ROI覆盖,其中每个测试ROI具有与特征模型相同的参数, 包括其重心。 然后,该方法包括对于每个测试ROI,计算由测试ROI限定的图像区域的强度时刻,并且如果测试ROI的质心偏离强度时刻,则将测试ROI移动到更接近强度时刻并重复这些步骤 直到质心和强度时刻基本上收敛,然后处理下一个测试ROI; 确定哪些ROI是候选ROI; 消除重复的ROI,其中两个或多个候选ROI识别相同的特征; 并输出候选ROI的列表,其候选位置识别所提供的图像中感兴趣的特征。
