Clean up

clear_deformable_model (ModelID)

如下是model:

如下是采样图片

以下是程序运行结果：

以下是代码的逐行解释：

dev_update_off()：关闭设备更新，以提高处理速度。

read_image (ModelImage, ‘food/cocoa_package_model’)：读取模型图像。

dev_close_window ()：关闭当前窗口。

dev_open_window_fit_image (ModelImage, , , -1, -1, WindowHandle)：打开一个窗口，窗口大小自动调整以适应图像。

set_display_font (WindowHandle, 16, ‘mono’, ‘true’, ‘false’)：设置窗口的显示字体。

创建并显示局部可变形模型：

create_local_deformable_model：创建一个局部可变形模型。

get_deformable_model_contours：获取模型的轮廓。

area_center：获取图像的中心点。

hom_mat2d_identity 和 hom_mat2d_translate：创建一个平移矩阵，将模型轮廓平移到图像中心。

affine_trans_contour_xld：使用平移矩阵变换模型轮廓。

dev_set_line_width (2)：设置线条宽度为2。

dev_set_color (‘yellow’)：设置线条颜色为黄色。

dev_display (ModelImage)：显示模型图像。

dev_display (ContoursAffinTrans)：显示变换后的模型轮廓。

disp_message：在窗口中显示消息。

disp_continue_message：在窗口中持续显示消息。

stop ()：暂停执行。

循环搜索图像：

read_image：读取要搜索的图像。

dev_resize_window_fit_image：调整窗口大小以适应图像。

dev_display：显示图像。

disp_message：显示搜索消息。

count_seconds：计算搜索开始时间。

find_local_deformable_model：在图像中搜索局部可变形模型。

count_seconds：计算搜索结束时间。

Time := S2 - S1：计算搜索时间。

gen_warped_mesh：生成变形网格。

dev_display：显示变形网格。

Found[Index] := |Score|：记录搜索得分。

disp_message：显示搜索结果。

if (Index < NumImages)：如果还有图像未搜索，显示继续消息并暂停。

clear_deformable_model (ModelID)：清除局部可变形模型。

这个脚本的主要功能是创建一个局部可变形模型，并在一系列图像中搜索这个模型，然后显示搜索结果和搜索时间。
