Check for Similarity / Identical Assets while uploading new Assets in DAM

[#1]

WHAT WE HAVE 

In AEM x.x.x version we have mechanism to check duplicate images being uploading in DAM which is supported by unique SHA1 value.This verification process is done during uploading of new Assets. 

1. By enabling duplicate OSGI  asset service 

2. OOTB mechanism is the SHA1 value check.

Currently ,  other way of achieving similarity/ identical  is by using Sensei which will be based on tags but this process is again done AFTER successful Asset upload and enabling of SMART tags to specific folders.

WHAT WE DO NOT HAVE 

We do not have mechanism where a Author WHILE uploading can know if there is any  similar / identical assets i.e. Assets which have been cropped or change in color shade etc. This should not be related to any property value check or SHA1 value instead check the pixels or any other parameter.

AUTHORING Challenges use case

In our current system we have thousands of pages with images of business leaders with different dimensions / cropped belonging to  different departments.The challenge for AUTHORS is if any leader resigns then his/her photo needs to be updated for the corresponding pages which can only be done after uploading a new photo in DAM. There is no way they can identify the pages where this new photo matches and then take necessary actions. The only one way they can achieve is by enabling SMART tags to the folders and then do Asset Search which is again driven by Tags.With our traditional approach of managing sites this is not possible mostly.

Hi @vijayt86226372 

The AEM already has duplicate asset detection mechanism as you know. This is working well for this purpose. I am not sure your specific use case fall into duplicate detection when  uploading the assets as the assets are already on the system and you seem to need a verification tool to find the pages/asset of interest. This is a very specific scenario than a common use case.

Hi hamid,

Thank you so much for your response ..!

Yes, i agree with your points on the already existing mechanism for duplicate check.

Our requirement is to check identical / Similar images in the system while uploading a new asset in DAM and not for duplicates.

Hi @vijayt86226372 

We discussed your use case internally and while we understand it we concluded this is a very specific scenario rather than a generic one that is used by other users. So for such use cases customization is a better approach to meet the business requirements. Thanks for your participation in the community.
