Use Segmentation to Improve Text Recognition 

Features under uneven illumination are typically not recognized correctly.

X -Graphics-

TextRecognize fails in this case and returns only a single "k" letter.

In[2]:=

X TextRecognize[image]

Out[2]=

Use locally adaptive segmentation to remove uneven illumination before text recognition.

In[3]:=

X b = LocalAdaptiveBinarize[image, 40, {0.85, 0.07}]

In[4]:=

X TextRecognize[b]
