What is edge detection?

Edge detection generally applies to a square wave signal, such as a clock pulse or a trigger pulse. Then the edge detection comes from either using the rising voltage, or the falling voltage of the signal (usually a square wave) to trigger the next event. Using the falling voltage implies a delay in the signal and the rising pulse to trigger an immediate `step` in the circuit.

Why smoothing and edge detection have conflicting aims?

Smoothing and edge detection have conflicting aims because smoothing aims to reduce noise and detail in an image to create a more uniform appearance, while edge detection seeks to highlight and identify abrupt changes in intensity or color that signify boundaries or features within the image. Smoothing can obscure these critical edges, making it harder to accurately detect them. Consequently, while smoothing enhances overall image quality, it can diminish the very details that edge detection relies on to function effectively. This inherent tension requires careful balancing in image processing tasks.
