Maximum range of yaw and pitches

[VIROBO-15]

Hi,

Can you please let me know what is the maximum range of yaw and pitches the GMPI can handle

[Xiaoming-Zhao]

We have not stress tested this.

But these two may give you a sense:

ml-gmpi/gmpi/curriculums.py

Lines 113 to 114 in 672294b

	'h_stddev': 0.289,
	'v_stddev': 0.127,

ml-gmpi/configs/gmpi.yml

Line 94 in 672294b

cam_pose_n_truncated_stds: 2

Essentially, during training, we use sample camera poses (or 3x for AFHQCat) within a 2x standard deviation. So GMPI should be able to handle [-2 * std, 2 * std] and extrapolate a little bit.

And for the video we showed, here is the angle range:

ml-gmpi/gmpi/eval/vis/render_video.py

Lines 235 to 240 in 672294b

	if horizontal_cam_move:
	face_angles = np.linspace(0.5, -0.5, 100).tolist()
	face_angles = [a + metadata["h_mean"] for a in face_angles]
	else:
	face_angles = np.linspace(0.3, -0.3, 100).tolist()
	face_angles = [a + metadata["v_mean"] for a in face_angles]
