hi thanks for your great work...can you please let me know what is the main difference between kernel and filter.

We have used the two words interchangingly. Hence you can consider the two words the same in our paper.

Could u please help me what exactly is ground truth kernel? as for Super-resolution we consider ground truth image to be the actually HR image and LR image to be the down-sampled version? So my doubt is what have we actually consider to be a ground truth kernel?

Here the ground truth kernel refers to the down-samling kernel used in the down-sampling process (Eqn. 2 in the paper). So the ground truth kernel can be specified for the synthetic HR and LR pair, while it is unknown for the real image.

thank you. does ground truth kernel means the kernels present actually in the LR image?
