    • The present invention suggests that a grid-shaped spreader be used for guiding and holding the branch pipes of a tube nest, especially in steam generators. The grid bar (1, 2) ends are fitted in slots provided on a single-piece central ring (3) which is surrounded on three sides by a C-shaped outer ring - seen in cross-section - with salient cross members (10), one in the upper part and one in the lower part. Each cross member is turned to the central ring (3) and engages in a groove (9) located opposite it in a front portion of said central ring (3) and in the notches provided in the grid bars (1, 2). The inventive spreader is intended to be placed mainly in steam generators as used in pressurized water reactor plants.

    • An edge detection process uses binary morphological erosion. For that purpose, a binary image (S1) is generated from the grey-tone input image (S). A structure element is progressively guided over the binary image (S1) and generates a shrunk binary image (S2) according to erosion rules. By calculating the difference between the first binary image and the shrunk binary image (S1, S2), an output image (Q1) in which the edges are preserved is generated. In a further development of the invention, a further erosion rule based on a grey tone threshold is applied to the eroded binary image (S2) and the difference between this grey tone-based eroded image (S3) and the input binary image (S1) is calculated to generate an output image (Q2) which also contains hidden edges.
    • 一种用于边缘检测方法使用二进制形态学消蚀。 为此,一个二进制图像(S1),从产生的灰度值的输入图像(S)获得。 的结构元件被引导逐步在二值图像(S1),并且根据一个侵蚀规范一个缩小二值图像(S2)中产生。 通过形成产生前者和geschrumfpten二进制图像(S1,S2)的差,边缘保留输出图像(Q1)。 在本发明中,含输出图像的auuch隐藏线(Q2)是由侵蚀二进制图象(S2)上施加控制,并且在基于侵蚀图像(S3)到所述输入侧的二值图像(S1)的灰度阈值进一步侵蚀说明书和差形成这种灰度值的定向。
