How to extract each character from the image?

[kushal-chakraborty]

I have done something like this.

`for cnt in contours:
if cv2.contourArea(cnt) > 20:
x,y,w,h = cv2.boundingRect(cnt)
cv2.rectangle(src_img,(x,y),(x+w,y+h),(0,0,0),1)
plt.figure()
plt.imshow(cv2.resize(src_img[y+2:y+h-2,x+2:x+h-2],(25,25)))
plt.show()

showimages()`

but it does not produce the expected result

In other words: how to use the software? Is there a documentation or publication?
