MORN question~ #69
Comments
您好,MORAN v1用的是两个维度的,即xy,但是我们发现cropped text基本没有水平位移的问题,所以MORAN v2去掉了x维度,只在竖直方向上纠正字符,能应用于大多数场景,同时也更好端到端训练,毕竟解空间变小了。 |
感谢回答!那我想问一下这个模型可以做不定长训练么?

您说的不定长指的是? |
在训练的时候固定图片的高度,然后等比例缩放长度。像CRNN一样

这个是可以实现的,您可以按照CRNN写一个alignCollate(dataset.py中),或者在MORN中随机缩放target_W。 |
好哒。谢谢!

请问第80行的代码应该是x_rectified = nn.functional.grid_sample(x, offsets_x) Lines 66 to 80 in 1eb6988
|
您好,原代码是对的,在纠正后的图像上预测offset,但是在原图x上采样。

还是x_rectified = nn.functional.grid_sample(x_rectified, offsets_x) ?

您好。我想问一下,在MORN里
图片过了CNN出来的size为什么是1311,而不是paper上写的2311呢?
还有,
MORAN_v2/models/morn.py
Lines 66 to 69 in 1eb6988
为什么只对y轴进行了矫正呢?还是我理解错了?
