排序学习总结

取每个对象的内接矩形框，然后再排序，根据排序的结果确定原对象顺序。

*扣图
reduce_domain (Image, Rectangle, ImageReduced)
*分割
threshold (ImageReduced, Regions, 150, 255)
connection (Regions, ConnectedRegions)
*筛选
select_shape (ConnectedRegions, SelectedRegions, 'area', 'and', 1475, 99999)
*求区域中心
area_center (SelectedRegions, Area1, Row, Column)
*在区域中心生成小圆
tuple_gen_const (|Row|, 20.5, Radius)
gen_circle (Circle, Row, Column, Radius)
*对小圆排序
sort_region (Circle, SortedRegions, 'character', 'true', 'row')
*得到排序后的中心坐标
area_center (SortedRegions, Area, Row1, Column1)
 
 
*显示结果
dev_display (ImageReduced)
set_display_font (WindowHandle, 14, 'mono', 'true', 'false')
count_obj (SortedRegions, Number)
for i:=1 to Number by 1    
    *根扰排序后坐标得到筛选区域索引
    get_region_index (SelectedRegions, Row1[i-1], Column1[i-1], Index)
    *根据索引选择区域，这个区域就是按顺序进行选中
    select_obj (SelectedRegions, ObjectSelected1, Index)
    *显示
    dev_display (ObjectSelected1)
    dev_disp_text (i, 'image', Row1[i-1]-10, Column1[i-1]-10, 'yellow', 'box', 'false')
