Final answer:
Iterative algorithm is not an example of a kernel.
Step-by-step explanation:
Kernel refers to the core or central component of an operating system that manages the system's resources and provides a layer of abstraction between the hardware and software.
Among the options given, iterative algorithm is not an example of a kernel. An iterative algorithm is a repetitive process that solves a problem by repeatedly updating the solution until it converges to the desired result.
On the other hand, options a) edge enhancement filter, b) smoothing filter, and c) standard convolution algorithm are examples of kernels used in image processing to modify images or perform mathematical operations.
