This paper presents a field programmable gate array (FPGA) based accelerated hardware architecture for Orientation Calculation in Scale Invariant Feature Transform (SIFT) for real time image registration. The orientation calculation part identifies the major orientations of feature points and helps in making the features invariant to rotational changes. This system is able to detect features upto...
Image enhancement is basically improving the interpretability or perception of information in images for human viewers and providing ‘better’ input for other automated image processing techniques. The principal objective of image enhancement is to modify attributes of an image to make it more suitable for a given task and a specific observer. This work addresses the implementation of image enhancement...
