pub mod img_hash {
	//! # The module brings implementations of different image hashing algorithms.
	//!
	//! Provide algorithms to extract the hash of images and fast way to figure out most similar images in
	//! huge data set.
	//!
	//! Namespace for all functions is cv::img_hash.
	//!
	//! ### Supported Algorithms
	//!
	//! - Average hash (also called Different hash)
	//! - PHash (also called Perceptual hash)
	//! - Marr Hildreth Hash
	//! - Radial Variance Hash
	//! - Block Mean Hash (modes 0 and 1)
	//! - Color Moment Hash (this is the one and only hash algorithm resist to rotation attack(-90~90 degree))
	//!
	//! You can study more about image hashing from following paper and websites:
	//!
	//! - "Implementation and benchmarking of perceptual image hash functions" [zauner2010implementation](https://docs.opencv.org/4.10.0/d0/de3/citelist.html#CITEREF_zauner2010implementation)
	//! - "Looks Like It" [lookslikeit](https://docs.opencv.org/4.10.0/d0/de3/citelist.html#CITEREF_lookslikeit)
	//!
	//! ### Code Example
	//!
	//! @include samples/hash_samples.cpp
	//!
	//! ### Performance under different attacks
	//!
	//! ![Performance chart](https://docs.opencv.org/4.10.0/attack_performance.JPG)
	//!
	//! ### Speed comparison with PHash library (100 images from ukbench)
	//!
	//! ![Hash Computation chart](https://docs.opencv.org/4.10.0/hash_computation_chart.JPG)
	//! ![Hash comparison chart](https://docs.opencv.org/4.10.0/hash_comparison_chart.JPG)
	//!
	//! As you can see, hash computation speed of img_hash module outperform [PHash library](http://www.phash.org/) a lot.
	//!
	//! PS : I do not list out the comparison of Average hash, PHash and Color Moment hash, because I cannot
	//! find them in PHash.
	//!
	//! ### Motivation
	//!
	//! Collects useful image hash algorithms into opencv, so we do not need to rewrite them by ourselves
	//! again and again or rely on another 3rd party library(ex : PHash library). BOVW or correlation
	//! matching are good and robust, but they are very slow compare with image hash, if you need to deal
	//! with large scale CBIR(content based image retrieval) problem, image hash is a more reasonable
	//! solution.
	//!
	//! ### More info
	//!
	//! You can learn more about img_hash modules from following links, these links show you how to find
	//! similar image from ukbench dataset, provide thorough benchmark of different attacks(contrast, blur,
	//! noise(gaussion,pepper and salt), jpeg compression, watermark, resize).
