data process

[alicera]

For data of training process,
If I have image size 100x160(h x w) and I want to design a 224 x 224 network.
How to deal with the images is better?

1. dirctly resize the image size 100x160 to 224x224
2. resize the image size 100x160 to 224x224 with padding 0

2 is better

Hi zhanghang
How about your data process for image resize?

Here is your process, right?
resize the image size 100x160 to 224x224 with padding 0
