Construction of a Novel Convolution Based Fractional Derivative Mask

This book presents a new approach in constructing a more efficient fractional derivative mask for image edge analysis based on the definition and properties of convolution. By the definition of convolution, the generalized Strivastiva-Owa's operator was rewritten with its order restricted to the Riemann-Liouville fractional derivative. Applying linearity, commutative and derivative properties of convolution to the resultant expression, a new mask with higher efficiency, memory effect and computational equivalence to the classical edge detector is developed as per the experimental results obtained. From the experimental results, it is observed that the new mask has the potency to find edges in details quite significantly as well as hidden edges which is a deficiency of the classical edge detectors.
