How to plot tissue regions returned by locate_tissue_cnts

Hello,

I am wondering if you can help me. Trying to understand how your tissue locator works. It looks like the locate_tissue_cnts function returns a list of coordinates for the various detected tissue region and the down-sampling level which is clear.

For your test image, the function returns 3 regions. How do you plot these coordinates? Do you have any pointers how i can overlay the coordinates on the image to check the accuracy?

I ran your function on one of my test images and I got 16 tissue regions. I am trying to figure out how to plot these coordinates.

Thank you kindly!

ValueError: not enough values to unpack (expected 3, got 2)

When i use the Python package the same as the given demo ,I met a error as:
File "E:/Pycharm project/maching learning/HW2/Try.py", line 10, in
cnts,d_factor = tl.locate_tissue_cnts(slide_path,max_img_size=2048,smooth_sigma=13,thresh_val=0.80,min_tissue_size=10000)
File "C:\Users\17807\AppData\Roaming\Python\Python37\site-packages\tissueloc\locate_tissue.py", line 146, in locate_tissue_cnts
cnts = find_tissue_cnts(bw_remove)

method=cv2.CHAIN_APPROX_NONE)
ValueError: not enough values to unpack (expected 3, got 2)

How can I solve this error? thanks first!
