Apply function to each pixel of the image

Is there a method in OpenCV which takes an input matrix, an output matrix and a function, and applies this function to each pixel? E.g a function like "check value of pixel, if it's below a certain threshold, set it to 0, otherwise keep the value"

I know I can iterate myself over the pixels of a matrix and apply the function myself, just wondering if there is a function which would save me this work.

You can easily create an appropriate LUT if you work with gray scale images.
