这项工作提出了一种二值图像表示的新方法和算法，用于快速有效地计算二值图像上的矩。这种二值图像表示方案称为图像块表示，因为它将图像表示为一组不重叠的矩形区域。图像块表示过程的主要目的是提供有效的二进制图像表示而不是图像的压缩。块表示的二进制图像非常适合在数字计算机中快速实现各种处理和分析算法。图像的二维（2-D）统计矩可用于图像处理和分析应用。已经提出了许多基于统计矩的强大形状分析方法，但它们存在计算成本高的缺点。通过利用块的矩形结构来实现块表示图像中矩的实时计算。
This work presents a new approach and an algorithm for binary image representation, which is applied for the fast and efficient computation of moments on binary images. This binary image representation scheme is called image block representation, since it represents the image as a set of nonoverlapping rectangular areas. The main purpose of the image block representation process is to provide an efficient binary image representation rather than the compression of the image. The block represented binary image is well suited for fast implementation of various processing and analysis algorithms in a digital computing machine. The two-dimensional (2-D) statistical moments of the image may be used for image processing and analysis applications. A number of powerful shape analysis methods based on statistical moments have been presented, but they suffer from the drawback of high computational cost. The real-time computation of moments in block represented images is achieved by exploiting the rectangular structure of the blocks.
