connection函数是Halcon库中的一个函数,用于将输入的区域连接成一个或多个连通区域。它的语法为:
connection (InputRegion, OutputRegion)
其中,CubeRegion是输入的区域,ConnectedRegions12是输出的连通区域。
该函数将输入的区域进行连接操作,将相邻的像素组成连通区域。输出的连通区域可以用于后续的形状分析、测量和处理等操作。
请注意,具体的使用细节和参数设置可能会因Halcon库的版本和具体需求而有所不同。建议参考Halcon库的官方文档或使用手册来获取准确的语法和参数设置。

mean_image (RegionTransImage, ImageMean3, 30, 30) dyn_threshold (RegionTransImage, ImageMean3, CubeRegion, 5, 'dark') connection (CubeRegion, ConnectedRegions12) select_shape (ConnectedRegions12, SelectedRegions17, 'area', 'and', 1000, 99999) select_shape (SelectedRegions17, SelectedRegions17, 'column', 'and', 50, 99999) count_obj (SelectedRegions17, Number13)
这段代码执行了一系列的图像处理操作。首先,使用`mean_image`函数计算`RegionTransImage`的均值图像,窗口大小为30x30,并将结果存储在`ImageMean3`中。
接下来,使用`dyn_threshold`函数对`RegionTransImage`进行动态阈值处理,使用`ImageMean3`作为阈值图像,并根据像素灰度进行阈值分割。将阈值范围内的像素设置为5,并将分割结果存储在`CubeRegion`中。
然后,使用`connection`函数对`CubeRegion`进行连接操作,将相连的区域合并成一个整体的区域对象,结果存储在`ConnectedRegions12`中。
接下来,使用`select_shape`函数根据区域的面积大小选择符合条件的区域,将结果存储在`SelectedRegions17`中。选择面积范围在1000到99999之间的区域。
然后,再次使用`select_shape`函数根据区域的列坐标选择符合条件的区域,并将结果覆盖存储在`SelectedRegions17`中。选择列坐标范围在50到99999之间的区域。
最后,使用`count_obj`函数计算`SelectedRegions17`中的区域对象数量,并将结果存储在`Number13`变量中。这段代码的目的可能是对特定区域进行阈值分割和形状选择,然后计算符合条件的区域对象的数量。
connection (RegionDilation, ConnectedRegions)
`RegionDilation` and `ConnectedRegions` are functions commonly used in image processing and computer vision.
`RegionDilation` is a morphological operation that expands or dilates regions in a binary image. It involves convolving the image with a structuring element, which is a small binary image that defines the shape and size of the dilation. The output of the operation is a new binary image where the regions have been expanded.
`ConnectedRegions` is a function that identifies connected components in a binary image. It groups together pixels that are connected to each other, either directly or indirectly, and assigns them a unique label. The output of the function is a labeled image where each pixel is assigned to a specific component.
In combination, these functions can be used to identify and analyze regions of interest in an image. For example, one might use `RegionDilation` to expand regions of interest, and then use `ConnectedRegions` to identify and label the resulting connected components. This can be useful for tasks such as object detection and tracking, or for analyzing the spatial distribution of features in an image.
