Hi, why are using <uint8_r> instead of the standard data types of opencv, for example <CV_8FC1> or <CV_64FC1> ? Good videos, keep it up.

These set of videos for image processing are the best!

Hi, what does "f" mean, when you're multiplying by 0.5f?

Let's say picture is of CV_16UC3, how to read each pixel value. Which vector we use. I'm not able to pixel values when image type is CV_16UC3

These tutorials are really helpful!  One question related to accessing pixels: How do you access pixels a small block at a time (5 pixel sliding window) for processing?  I have searched and tried a bunch of things without much success.  Can you transfer a Mat object to a preallocated array of int by reference and then transfer back to a Mat object after processing?

Is it better to access pixels like this or is it better to use pointers?
