This paper provides an image shape representation technique known as Adaptive Kernel Density Feature Points Estimator (AKDFPE). In this method, the density of feature points within defined rings (bandwidth) around the centroid of the image is obtained in the form of a vector. The AKDFPE is then applied to the vector of the image. AKDFPE is invariant to translation, scale and rotation. This method of image representation shows improved retrieval rate when compared to Kernel Density Feature Points Estimator (KDFPE) method. Analytic analysis is done to justify our method, which was compared with the KDFPE to prove its robustness.
