Shape-based Object Retrieval and Classification with Supervised Optimisation

In order to enhance the performance of shape retrieval and classification, in this paper, we propose a novel 
 
shape descriptor with low computation complexity that can be easily fused with other meaningful descriptors 
 
like shape context, etc. This leads to a significant increase in descriptive power of original descriptors without 
 
adding to much computation complexity. To make the proposed shape descriptor more practical and general, 
 
a supervised optimisation strategy is introduced. The most significant scientific contributions of this paper 
 
includes the introduction of a new and simple feature descriptor with supervised optimisation strategy leading 
 
to the impressive improvement of the accuracy in object classification and retrieval scenario.
