    • A system, method and program product for camera-based object analyses including object recognition, object detection, and/or object categorization. An exemplary embodiment of the computerized method for analyzing objects in images obtained from a camera system includes receiving image(s) having pixels from the camera system; calculating a pool of features for each pixel; then deriving either a pool of radial moment of features from the pool of features and a geometric center of the image(s) or a pool of central moments of features from the pool of features; then calculating a normalized descriptor, based on an area of the image(s) and either of the derived pool of moments of features; and then based on the normalized descriptor, a computer then either recognizes, detects, and/or categorizes an object(s) in the image(s).
    • 一种用于基于相机的对象分析的系统,方法和程序产品,包括对象识别,对象检测和/或对象分类。 用于分析从相机系统获得的图像中的物体的计算机化方法的示例性实施例包括从相机系统接收具有像素的图像; 计算每个像素的特征池; 然后从特征池中获得特征的径向力矩池,以及图像的几何中心或来自特征池的特征的中心时刻池; 然后基于图像的面积和所导出的特征矩的任一个来计算归一化描述符; 然后基于归一化描述符,计算机然后识别,检测和/或分类图像中的对象。

    • Homography-based imaging apparatus and method are provided. The apparatus may include a processor (44) coupled to process respective sequences of sky images respectively acquired by physical image acquisition devices 181 and 182 at respective spaced apart locations (e.g., P1, P2). The processor may include an image alignment module (32) configured to spatially relate respective views of at least one object (e.g., clouds, aerial vehicles) visible in the respective sequences of the sky images based on homography (42) of at least one astronomical image acquired at each spaced apart location. The astronomical image may include a number of spatial references corresponding to respective astronomical body positions located practically at infinity relative to a respective distance between the spaced apart locations. Further views (synthetic views) may be generated at selectable new locations (e.g., P3, P4, P5, P6), without actually having any physical image acquisition devices at such selectable locations.
    • 提供基于成像的成像装置和方法。 该装置可以包括处理器(44),其被处理器(44)耦合以处理在相应的间隔开的位置(例如,P1,P2)处分别由物理图像采集装置181和182获取的天空图像的各个序列。 处理器可以包括图像对准模块(32),其被配置为基于至少一个天文学的同位素(42)空间上关联在天空图像的相应序列中可见的至少一个对象(例如,云,空中飞行器)的各个视图 在每个间隔开的位置获取图像。 天文图像可以包括对应于相对于相对于间隔开的位置之间的相应距离实际上位于无穷远处的相应天文体位置的多个空间参考。 可以在可选择的新位置(例如,P3,P4,P5,P6)处产生进一步视图(合成视图),而在这种可选择位置实际上没有任何物理图像采集装置。
