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.

The frame memory is made up of a plurality of memory planes which are logically stacked in a depth direction (Z direction) and are accessed independently. The apparatus also includes a memory controller which can access a plurality of memory areas of the frame memory. These memory areas can be located in any desired position in the depth direction, and can each have a desired number of bits in the depth direction, regardless of a bit length of image buses contained in the apparatus and connected to an image processor, and the memory controller. The image processor receives data through the image buses, logically operates the data and outputs it to the image buses. When in read mode, the memory controller converts the data read out from the memory areas of the frame memory into the type of data which can be transferred through the image buses.

Abstract: First and second images as stereoscopic images of an object are obtained. The second image is shifted by a value dx. Absolute values of differences between image data of the shifted image and the first image are calculated, thus obtaining a third image. The third image is subjected to average value filtering to obtain a fourth image. A fifth image which has the same size as that of the fourth image and has a maximum gray level in an initial state is prepared. Image data having a smaller value is selected from image data of the fourth and fifth images to obtain a sixth image. Absolute values of differences between image data of the sixth and fifth images are calculated, thus obtaining a seventh image having the calculated absolute values as image data. A ninth image which has the same size as that of the seventh image. When the gray level of the pixel of the sevength image is 0, an eighth image is obtained to have the image data of the ninth image.

Abstract: A hot isostatic pressing apparatus which includes a pressure vessel, a heater and a heat-insulating layer interposed between the pressure vessel and heater. The heat-insulating layer is formed of at least two layers, i.e., an inner layer and outer layer. The inner layer embraces an object, which is under treatment, and the heater. The inner layer is loadable in and unloadable from the pressure vessel together with the object and heater while maintaining a space, which is embraced by the inner layer, in a state hermetically isolated from the surrounding atmosphere. However, the outer layer is held within the pressure vessel. When the hot isostatic pressing apparatus is incorporated in a modular HIP system, the cooling time is considerably shortened and the efficiency of the HIP treatment is hence improved to a considerable extent.
