Provided methods

`pub fn compute( &mut self, input_arr: &dyn ToInputArray, output_arr: &mut dyn ToOutputArray ) -> Result<()>`[src]

Computes hash of the input image

Parameters

inputArr: input image want to compute hash value
outputArr: hash of the image

`pub fn compare( &self, hash_one: &dyn ToInputArray, hash_two: &dyn ToInputArray ) -> Result<f64>`[src]

Compare the hash value between inOne and inTwo

Parameters

hashOne: Hash value one
hashTwo: Hash value two

Returns

value indicate similarity between inOne and inTwo, the meaning of the value vary from algorithms to algorithms
