当你从Tim Cootes网站下载aam项目时,它应该有你开始需要的一切。

我建议在linux上运行带有“wine”的windows二进制文件。linux二进制文件依赖于一些过时的库,这些库需要一些努力才能正确安装。
该项目有几个关键文件夹:图像、点、模型、win_bin。“images”是包含图像文件的文件夹,它们对应的.pts文件将转到“points”文件夹。
“models”文件夹包含用于构建模型的configuration.smd文件。附带的smd文件示例如下所示:
~/Documents/am_tools/models$ cat tim_face.smd
// List of images + parameters required to define type of model
// Note: List excludes images in the separate test set (tim_face_test.smd)
model_name: tim_face
model_dir: ./
parts_file: face
image_dir: ../images/
points_dir: ../points/
shape_aligner: align_similar_2d
shape_modes: { min: 0 max: 30 prop: 0.98 }
tex_modes: { min: 0 max: 40 prop: 0.99 }
combined_modes: { min: 0 max: 30 prop: 0.99 }
params_limiter: mdpm_box_limits
{
sd_limits: 3
}
n_pixels: 10000
colour: Grey // Alternatives: Grey,RGB,...
// Texture Sampler can be tri_raw, tri_edge...
tex_sampler: vapm_triangle_sampler<vxl_byte>
tex_aligner: align_linear_1d
// shape_wts define how to compute relative scaling of shape & tex.
// shape_wts can be `EqualVar', `EqualEffect',...
shape_wts: EqualVar
// tex_model defines type of model to represent texture statistics, eg: pca, pca+haar1d
tex_model: pca
// Image Pyramid Builder can be gauss_byte, gauss_float, grad_float ...
pyr_builder: gauss_byte
points_pyr_builder: Same
max_im_pyr_levels: 5
// Levels of multi-res model to build :
min_level: 0
max_level: 4
// Details of points : images
training_set:

107_0764.pts : 107_0764.jpg
107_0766.pts : 107_0766.jpg
107_0779.pts : 107_0779.jpg
107_0780.pts : 107_0780.jpg
107_0781.pts : 107_0781.jpg
107_0782.pts : 107_0782.jpg
107_0784.pts : 107_0784.jpg
107_0785.pts : 107_0785.jpg
107_0786.pts : 107_0786.jpg
107_0787.pts : 107_0787.jpg
107_0788.pts : 107_0788.jpg
107_0789.pts : 107_0789.jpg
107_0790.pts : 107_0790.jpg
107_0791.pts : 107_0791.jpg
107_0792.pts : 107_0792.jpg
}
只需确保列出的.pts和.jpg文件存在于图像和点文件夹中即可。接下来运行am_build_apm.exe/am_build_aam.exe命令:
~/Documents/am_tools/win_bin$ wine am_build_apm ../models/tim_face.smd
这将在win_bin文件夹中创建tim_face.apm文件。现在可以通过运行以下命令查看创建的模型:
~/Documents/am_tools/win_bin$ wine am_view_apm.exe
并在应用程序菜单中打开~/Documents/am_tools/models/tim_face.smd文件。
现在在.smd文件中使用不同的参数,尝试用pts文件添加您自己的图像,我认为BioID数据库有几百个用.pts文件注释的图像。
