## Modification I changed the hardcoded 3 channel length to dynamic channel length in `np.full` function arguments. This modification enables `RandomMosaic` transform to support multispectral image (e.g. RGB image with NIR band) or bi-temporal image pairs for change detection task. ## Checklist 1. Pre-commit or other linting tools are used to fix the potential lint issues. 2. The modification is covered by complete unit tests. If not, please add more unit test to ensure the correctness. 3. If the modification has potential influence on downstream projects, this PR should be tested with downstream projects, like MMDet or MMDet3D. 4. The documentation has been modified accordingly, like docstring or example tutorials.
