Hi, after reading your paper (https://arxiv.org/pdf/2107.14599.pdf) I have a question on SNE-RoadSeg+ you proposed. The solution to the extreme problem in equation (3) is not so trivial. Can you give...
Hi, in your code you normalize xx_channel and yy_channel as following: https://github.com/uber-research/CoordConv/blob/27fab8b86efac87c262c7c596a0c384b83c9d806/CoordConv.py#L70 https://github.com/uber-research/CoordConv/blob/27fab8b86efac87c262c7c596a0c384b83c9d806/CoordConv.py#L71 I think it should be: `xx_channel = tf.cast(xx_channel, 'float32') / (self.y_dim - 1)` `yy_channel = tf.cast(yy_channel, 'float32')...
Hi, the line parameters solving in your code involves eigenvalues. Can you show me a formula derivation about this implementation. I tried to do it by myself but failed. Thank...
Hi, what's the meaning of project_matrix_ and pitch_diff_ in class LaneDetectionComponent? They are set in InitProjectMatrix function as [https://github.com/ApolloAuto/apollo/blob/master/modules/perception/onboard/component/lane_detection_component.cc#L528-L541](url) It seems that project_matrix_ represents transform from pixel coordinates in one...
In the paper, you said "We use the same scale factor σ as described in Section 3.4 to normalize the position offsets within a sensible range". But in your code...
Why only use x coordinate of projection of an object's position to determine visible when doing random_crop?
In the paper you said "The model is trained using SGD for 600 epochs with a batch size of 8, momentum of 0.9 and learning rate of 10−7". Why we...
Hello, Thank you for your nice work. I really can't understand the meaning of post_rots and post_trans. Can you give an explaination about it ? Thank you again.
How does `singleMove1` and `doubleMove1` come from? Is 0.3 obtained by experiments?
https://github.com/url-kaist/TRAVEL/blob/ea9520a7469d37809df7c4eaeb36b9ff8c4490e1/include/travel/tgs.hpp#L878 There is an abs for `normal_similarity` in paper. Is this a typo? By the way, can you give some reference on the equation (2) in paper?
