tree's canopy. Image segmentation. Thresholding problem
 

The problem is that when thresholding image segmentation is performed, it is impossible to separate the sky and the background, the trunk of the tree is constantly added to the sky, from which sunlight is reflected. I tried several methods, for example, separation by RGB channels, but this did not help. If anyone, please, have experience or advice, how can you segment these types of images more accurately?
