thanks for the contributions

iam running fit-model-ceres code for creating of 4d face , while running the fit-model-ceres code in the model arguments ("../share/sfm_3448.bin "). but i did not seen sfm_3448.bin file in the share folder. where i need to download that .i though that there is a spelling error so i used sfm_shape_3448.bin. i got below error. where can i download the 4d file

ImageCost requires a model that co ntains a colour PCA model. You may want to use the full Surrey Face Model, a different morphable model, or

advance thanks for all the help and contributions

Hi @ranjith502,

Apologies for the late reply, I must have missed the GitHub notification. The Readme contains information and a link to the full model (https://github.com/patrikhuber/eos?tab=readme-ov-file#the-surrey-face-model) from Uni Surrey or alternatively the 4DFM. There are also two big notes & comments in the fit-model-ceres.cpp code here https://github.com/patrikhuber/eos/blob/8196a74659ac0987259bbd54d2960e19bed28e49/examples/fit-model-ceres.cpp#L78-L84 and here https://github.com/patrikhuber/eos/blob/8196a74659ac0987259bbd54d2960e19bed28e49/examples/fit-model-ceres.cpp#L367-L373, exactly at the place where the error you got is printed.
