Error when using the BFM model about 4dface HOT 7 CLOSED

Hi,

The warning is just exactly what it says: The BFM doesn't come with texture coordinates, so unless you add some, anything requiring texture remapping will naturally not be available.

Not sure where the OpenCV errors come from. You'll have to check which line it occurs. Note that BFM support is somewhat alpha-status so unless you are willing to get your hands dirty and know how to run a debugger, I would not recommend going that route.
We hope to improve BFM support in the future.

Hi

I think the problem in the rows of the matrix is negative. How can I solve it please? Is the problem in the conversion process?

4dface.exe!cv::Mat::create(int _rows, int _cols, int _type) Line 354 C++

this 0x00000000001c3ae8 {flags=1124008870 dims=2 rows=-331695445 ...} cv::Mat *

I think you may just be running out of memory (RAM)? Though the BFM basis matrix is only about 70k x 200, so not too big. Shouldn't be an issue.
Can I please recommend that you use an up-to-date eos version (i.e. v0.12.1), not the one from the 4dface submodule. eos evolved a lot and now uses Eigen to represent model data.

Still, I think this is most likely some issue with your system.

Hi

I uploaded the new version of 4dface, but when I tried to run the cmake I got this error

CMake Error at C:/Program Files/CMake/share/cmake-3.6/Modules/FindPackageHandleStandardArgs.cmake:148 (message):
Could NOT find Eigen3 (missing: EIGEN3_INCLUDE_DIR EIGEN3_VERSION_OK)
(Required is at least version "2.91.0")
Call Stack (most recent call first):

cmake/FindEigen3.cmake:76 (find_package_handle_standard_args)
CMakeLists.txt:74 (find_package)

It is because of Eigen package, I need to use the Eigen that in eos how can I set that ?

from 4dface.

Please follow the instructions in the README of eos. (you may also need to clear the CMake cache)

(Note that the newer eos version may not work out of the box with this current 4dface version, be prepared to make some adjustments, if you want to combine these two. It's easy to do for someone with a bit of programming experience but it's not an out-of-the-box supported use-case at the moment.)

Is BFM better than Surrey model?

Is BFM better than Surrey model?

This question does not have a yes/no answer. Among many other differences, the BFM is a high-res, high-quality model, capturing face, ear and neck area. The SFM comes in many resolution levels (from 845 vertices to 30k), a public shape model, and expressions. There are many use-cases for both of them, and there's many publications out there describing both of the models in detail.

I'm going to close this issue as off-topic.
