centos rpm package description list?

[hadi motamedi <motamedi24@xxxxxxxxx>]

Dear All
Is there any reference link that lists the centos rpm packages by
their description? As I know, we have reference sites like
rpm.pbone.net and dag.wieers.com etc that we can search for an rpm
package by its name. But what we have if we want to find a rpm package
by its description rather than its name? Say we want to find how many
solutions do we have for Image processing or Speech processing on
centos, so if we know the solution is GIMP so we can search for its
rpm package on the mentioned sites but what we can do if we just know
the rpm package description?
Thank you
