描述

算子 merge_regions_line_scanmerge_regions_line_scanMergeRegionsLineScanMergeRegionsLineScanMergeRegionsLineScanmerge_regions_line_scan connects adjacent regions, which were segmented from adjacent images with the height ImageHeightImageHeightImageHeightImageHeightimageHeightimage_height. This operator was especially designed to process regions that were extracted from images grabbed by a line scan camera. CurrRegionsCurrRegionsCurrRegionsCurrRegionscurrRegionscurr_regions contains the regions from the current image and PrevRegionsPrevRegionsPrevRegionsPrevRegionsprevRegionsprev_regions the regions from the previous one.

With the help of the parameter MergeBorderMergeBorderMergeBorderMergeBordermergeBordermerge_border two cases can be distinguished: If the top (first) line of the current image touches the bottom (last) line of the previous image, MergeBorderMergeBorderMergeBorderMergeBordermergeBordermerge_border must be set to 'top'"top""top""top""top""top", otherwise set MergeBorderMergeBorderMergeBorderMergeBordermergeBordermerge_border to 'bottom'"bottom""bottom""bottom""bottom""bottom".

If the operator merge_regions_line_scanmerge_regions_line_scanMergeRegionsLineScanMergeRegionsLineScanMergeRegionsLineScanmerge_regions_line_scan is used recursively, the parameter MaxImagesRegionMaxImagesRegionMaxImagesRegionMaxImagesRegionmaxImagesRegionmax_images_region determines the maximum number of images which are covered by a merged region. All older region parts are removed.

算子 merge_regions_line_scanmerge_regions_line_scanMergeRegionsLineScanMergeRegionsLineScanMergeRegionsLineScanmerge_regions_line_scan returns two region arrays. PrevMergedRegionsPrevMergedRegionsPrevMergedRegionsPrevMergedRegionsprevMergedRegionsprev_merged_regions contains all those regions from the previous input regions PrevRegionsPrevRegionsPrevRegionsPrevRegionsprevRegionsprev_regions, which could not be merged with a current region. CurrMergedRegionsCurrMergedRegionsCurrMergedRegionsCurrMergedRegionscurrMergedRegionscurr_merged_regions collects all current regions together with the merged parts from the previous images. Merged regions will exceed the original image, because the previous regions are moved upward (MergeBorderMergeBorderMergeBorderMergeBordermergeBordermerge_border='top'"top""top""top""top""top") or downward (MergeBorderMergeBorderMergeBorderMergeBordermergeBordermerge_border='bottom'"bottom""bottom""bottom""bottom""bottom") according to the image height. For this the system parameter 'clip_region'"clip_region""clip_region""clip_region""clip_region""clip_region" (see also set_systemset_systemSetSystemSetSystemSetSystemset_system) will internally be set to 'false'"false""false""false""false""false".

执行信息

• 多线程类型：可重入（与非独占算子并行运行）。
• 多线程作用域：全局（可从任何线程调用）。
• 未采用并行化处理。
