In the line xx1 = np.maximum(x1[i], x1[order[1:]]) below it throws this error in FaceBoxes\utils\nms\py_cpu_nms.py

It seems that you do not use the cython version of NMS?

I got compilation error so I uncommented this line and commented the next one

I am on Windows 10 FWIW

I changed to the following in FaceBoxes/utils/nms/cpu_nms.pyx after lots of tries and it seems to be working (in progress)

def cpu_nms(np.ndarray[np.float32_t, ndim=2] dets, np.float thresh):
    cdef np.ndarray[np.float32_t, ndim=1] x1 = dets[:, 0]
    cdef np.ndarray[np.float32_t, ndim=1] y1 = dets[:, 1]
    cdef np.ndarray[np.float32_t, ndim=1] x2 = dets[:, 2]
    cdef np.ndarray[np.float32_t, ndim=1] y2 = dets[:, 3]
    cdef np.ndarray[np.float32_t, ndim=1] scores = dets[:, 4]

    cdef np.ndarray[np.float32_t, ndim=1] areas = (x2 - x1 + 1) * (y2 - y1 + 1)
    cdef np.ndarray[np.int64_t, ndim=1] order = scores.argsort()[::-1]

    cdef int ndets = dets.shape[0]
    cdef np.ndarray[np.int64_t, ndim=1] suppressed = \
            np.zeros((ndets), dtype=np.int64)

I have found a similar issue: eragonruan/text-detection-ctpn#380. BTW, good luck : )

zubair-ahmed-ai commented

I also had to do below in two places in demo_video.py

if len(boxes) == 0:
  continue

I got the idea from that post myself, my above fix worked.

If this fix works across platforms, welcome for your PR : )

if you got "cl : Command line error D8021 : invalid numeric argument '/Wno-cpp'" error
modify 47 line of build.py to extra_compile_args=['std=c99'],

do you know how to generate the 3D render picture with color?
thanks.

@chenbolinstudent
the first version of 3DDFA has implement code.
I think you can refer to that code

@chenbolinstudent face3d this project will help you.

it only transfer .mat to png ?
not transfer .obj to png?

I can not transfer .obj to png.
can you do it ?

@JacksonL1 @cleardusk I can not transfer .obj to png. can you do it ?

use trimesh module.

On windows10, please uncomment extra_compile_args={'gcc': ["-Wno-cpp", "-Wno-unused-function"]}, in FaceBoxes/utils/build.py line 46
