ABSTRACT:
A first memory stores a divided three-dimensional binary image as image data j of p bits. A second memory, equal to the first memory in size, stores data k of q bits, representing the section number of a corresponding memory section of the first memory. A histogram computing circuit concatenates data j and data k and obtains a histogram for the concatenated data. A computing unit computes a marginal distribution of the three-dimensional image on the basis of the histogram. A data conversion unit converts the p bit data to a first data image. An adder unit obtains from the first image a second image representing the marginal distribution P(x,y). The computing unit computes a marginal distribution P(x) and a marginal distribution P(y) from the second image, and also computes the volume and center of gravity of the three-dimensional binary image.
