Histogram equalization is good when histogram of the image is confined to a particular region. It won't work good in places where there is large intensity ...

2: Histogram Equalization - OpenCV

In this, image is divided into small blocks called “tiles” (tileSize is 8x8 by default in OpenCV). Then each of these blocks are histogram equalized as usual.

Histogram Equalization

It is a method that improves the contrast in an image, in order to stretch out the intensity range (see also the corresponding Wikipedia entry).
