Mat stands for Matrix and is contained in the namespace of OpenCV. They are represented using a type number of a certain manner.

cv_8uc1 is an 8-bit single-channel array. It has 2 parts, the depth, and various numbers of channels. There is a flexible system that is enough to let the users define some new types with up to 215 channels. CV_8UC1 makes the code more clear that how many numbers of channels is the code is working with. If someone is dealing with a matrix that contains 10 channels or even more than that, the person needs to specify the number of channels that will be included.
