The AverageHash does not seem to be available.
The Perceptual Hash function returns an object per channel (red/green/etc..) with 14 doubles that are calculated using the image moments. I will create a class with a method that will allow you to get the distance of a channel of two images. The lower this number the more equal the channel. I will also add something to easily convert this to and from a string.
