Local feature description is to assign a unique signature to a key-point such that it becomes
distinctive from the others regardless of changes in viewpoint, illumination, rotation, scale as
well as distortions and noise. This paper proposes a novel approach to construct such a descriptor.
For preserving both homogeneous and heterogeneous features of a given support region, we
interweave the texture information so that the key-point is more likely to be assigned a distinctive
signature and neighboring key-points will be less likely to share the same texture information.
The main idea behind our descriptor is to increase the areas of our observations in the given
scene while the length of the local support region is fixed. Gradient magnitude and divergence,
as measurement parameters of texture information, are applied to a group of pixels instead of
employing a pixel-wise strategy that make the descriptor more resistant to noise, distortions
and illumination variation. The required storage of the proposed descriptor is just 72 floats
and its computational complexity is much lower than those of existing ones. A comparative
study between the proposed method and the selected state-of-the-art ones over multiple publicly
accessible datasets with different characteristics shows its superiority, robustness and computational
efficiency under various geometric changes, illumination variation, distortions and noise.
