The `Mat.At` function in C# is used to access and retrieve pixel values from an OpenCV `Mat` object.
`Mat` is a matrix class in OpenCV which represents an image or a multi-dimensional array. The `Mat.At` function allows you to retrieve the value of a specific pixel in the matrix by specifying the row and column indices.
The function takes two parameters: the row index and the column index of the pixel you want to access. The result is the pixel value at the specified location.
For example, if you have a `Mat` object called `image`, you can retrieve the pixel value at row 2 and column 3 using `image.At(2, 3)`. This will return the value of the pixel at that location.
Note that the `Mat.At` function returns the pixel value as an array of values, where each value represents the intensity or color channel at that pixel. The number of values returned depends on the type of the `Mat` object, such as grayscale or color image.
