# Function to find joint probability and conditional probability in OpenCV

Is there any built-in function to find Joint Probability and Conditional Probability of images in OpenCV! What does the function "CalcProbDensity" does? OpenCV documentation explanation says divide one histogram by other histogram. Can someone give a bit more elaborate explanation?

## Comments

- please explain: "Joint Probability and Conditional Probability of images" -- what's the context ?
- if you meant this -- it's dead and gone, please use current opencv code, and current documentation
- please have a look at the faq , and try to improve your question
