＜Halcon＞分割粘连区域

read_image (Image, 'F:/培训/Halcon培训/2.jpg')
rgb1_to_gray (Image, GrayImage)

*平滑图片去噪
mean_image (GrayImage, ImageMean, 3, 3)
get_image_size (ImageMean, Width, Height)

*截取中心ROI区域
gen_circle (ROI_0, 480, 490, 450)
reduce_domain (ImageMean, ROI_0, ImageReduced)

threshold (ImageReduced, Regions, 96, 234)
connection (Regions, ConnectedRegions)
select_shape (ConnectedRegions, SelectedRegions, 'area', 'and', 200, 99999)

*计算输入区域(或其补码)的每个点到区域边界的距离
*参数Foreground决定是为区域内的所有点计算距离(Foreground= 'true')
*区域外的所有点计算距离(Foreground= 'false')
distance_transform (SelectedRegions, DistanceImage, 'euclidean', 'true', Width, Height)
invert_image (DistanceImage, ImageInvert)

*图像比例增强 按最大比例增强对比度
scale_image_max (ImageInvert, ImageScaleMax)

*分水岭算法
watersheds_threshold (ImageScaleMax, Basins, 15)
gen_contour_region_xld (Basins, Contours, 'border')

*取出两个区域中重叠的部分
intersection (Basins, SelectedRegions, RegionIntersection)
