Layout indexing of trademark images
Ensuring the uniqueness of trademark images and protecting their identities are the most important objectives for the trademark registration process. To prevent trademark infringement, each new trademark must be compared to a database of existing trademarks.

Our framework starts by segmenting trademark ima...
