Hi Steve, yes, I would like to have finer control of block/kernel size to obtain similar results if I apply this to small test patches or the larger complete image. Is there any reason to limit ntiles_x/y to 16? Regards, Kai Am Mittwoch, 27. Mai 2015 03:17:01 UTC+2 schrieb Steven Silvester:
Hi Kai,
Is the issue that you want finer grain control of the block size? If so, that would require a substantial rewrite.
Please feel free to open an issue on Github if that is the case.
Regards,
Steve

Hi Steve,
but these parameters are limited to the range 1..16. The small test patches are 150x150 pixels, the complete images have 1920x1448 pixels. I have applied equalize_adapthist here with default parameters (n_tiles=8).
Best regards,
Kai

Hi Kai,
Do the `n_tiles*` arguments not meet your needs? By defining the number of tiles in X and Y, you are equivalently setting a block size.

I am using equalize_adapthist after color deconvolution and some morphological operations to enhance local contrast of nuclei in histological images. There are different results when applying equalize_adapthist when using small patches and larger size whole images (left small patch, right large size whole image). The CLAHE implementation in ImageJ has a 'block size' parameter and the implementation in Pixinsight has a 'Kernel size' parameter to get results depending on the local context. Is it possible to 'simulate' this behaviour with scikit-image?
Best regards,
Kai
