[FEATURE]: Reverse image search based on image hashes

[zamanmub]

Is there an existing issue for this?

• I have searched the existing issues

Is your feature request related to a problem? Please describe.

My team wanted to search image similarity based on hashes. I couldn't find any tutorial or documenation for it

Describe the solution you'd like

A Jypyter Notebook based tutorial to get started. Since Milvus doesn't support string types, converting hashes to binary vector is the way to go

Describe alternatives you've considered

A Docker deployable solution

Anything else?

N/A

@generalZman That's a good idea, and which image hash do you think is better? Actually, you only need to modify the encode function to hash in the jupyter, and when inserting Milvus with DataType.Binary and Hamming metric_type. For more details, you can refer to this example by searching binary.

So can you contribute the function of image hashing to Bootcamp? We will welcome you to become a member of the Milvus Bootcamp community.

@shiyu22 Thanks for the pointers. I am working on it now as part of Hacktoberfest. I will be using pHash for the tutorial.
