Etymology: "Denoises" is the third-person singular present form of "denoise," so its history is the history of that verb. "Denoise" is built from the prefix "de-," meaning "remove or reverse," attached to "noise," which came into English from Old French "noise," meaning outcry or quarrel. The prefix turns the sense into "remove the noise," which is exactly what the verb describes in audio, image, and data processing. The base word has traveled a long way from its modern sense. "Noise" originally meant a clamor, a quarrel, or a loud outcry, and only later broadened to any unwanted sound and then to unwanted random variation in signals. "Denoise" follows that path in reverse: it names the act of stripping that unwanted variation back out. The verb is a modern technical formation, so it belongs to the vocabulary of signal processing rather than to older English.
