feature

hi, I am doing some face detection stuff. Now, I can run the code under project\viola-jones. I want to have the CC3_FACE_FEATURESi. However, I found the CC3_FACE_FEATURESi in project\viola-jones\vj.h is different from the features in project\viola-jones\vj.h and CC3_FACE_FEATURESi does not have features for CC3_SCALES = 21. In short, my questions is could I find the CC3_FACE_FEATURESi for CC3_SCALES=21. anywhere or the Matlab script, generate_feat_in_struct_for_C.m .

Thanks for your help.

    The minimum scale size for the face was chosen to be 30 to speed up the detection process. Even during the training, the face size was 24x24, so you might not want to go below this resolution. But if you absolutely want to, you can run the generate_feat_in_struct_for_C.m with new "scale" parameters, for example, scales = [20, 30, 38, 48 , 60] (assuming you have features.mat file). This will save the whole feature data structure in a text file which you can copy and paste to the vj.h file.

    Hope that helps.

      Thanks for your answer. I can have features.mat from original vj.h file. Now, the problem is where I can find generate_feat_in_struct_for_C.m file. Can I find this file from some zip file? I download cmucam3_install.zip(114 MB) but couldn't find it. Could you point out which directory it is or where I can download this file. Thanks a lot for your help.

        I posted the matlab code on the viola-jones page. It is at the bottom under "Extra Utilities".

          Hi,

          M-file generate_feat_in_struct_for_C.m appears to be using a function called get_scaled_feature. Would it be possible for you to post this file, too? Without it, generate_feat_in_struct_for_C doesn't work. Would you also be able to post features.mat?

          Thanks.

        Hi,could you tell me how to get the "features.mat" for detail.I don't know how to get this file.Thank you for your help.
