If you accidentally like someone else's Instagram photo and then unlike it, the notification will be removed. This means that the person will only be able to know that you accidentally liked their photo if they're using the app while you're doing it.
If the person is using the app while you accidentally like then unlike their photo, they will be notified for a moment. On the other hand, if the person is not on the app while you accidentally like then unlike their photo, they won't be notified unless they have turned on Instagram notifications.
It all depends on timing and this is why: If you like someone's Instagram post, they will receive a notification. However, the moment you unlike the post, the notification will be removed. If the person whose post you accidentally liked was online right at that moment, they would see the notification.
