How to Reposition and Reassemble Image Patches After Grid Extraction

[6rid9e]

Hello, thanks for your contributions，after using grid extraction to divide the image into patches, I need to process the patches and finally recombine them into a whole slide image (WSI). Could you please help me how to deal with the code to correctly position these patches back into their original places? Thank you for your help.

Hi @6rid9e,

you can find the extraction coordinates of the tile in the filename itself, in the format {prefix}tile_{tiles_counter}_level{level}_{x_ul_wsi}-{y_ul_wsi}-{x_br_wsi}-{y_br_wsi}{suffix}.
Please consider that these coordinates are referring to the size of the WSI at level 0.

Moreover, if you used the GridTiler, the tiles are extracted and saved in order, row by row, so it should be easy to recombine the tiles afterwards.
