You will be shown an excerpt from a computer science scientific research paper, followed by a question about the paper. Please answer the question. Do not include any text in your response other than the answer.

Context: Data preparation is similar to SRCNN [5] with some differences. Input patch size is now equal to the size of the receptive field and images are divided into sub-images with no overlap. A mini-batch consists of 64 sub-images, where sub-images from different scales can be in the same batch.

Question: Difference between data preparation for the proposed model and the SRCNN?
The proposed model's input size is the same as the receptive field size, and images were divided with no overlap.
