Local contrast enhancement is a technique to enhance the visibility of local details of an image by increasing the contrast in local regions. Adaptive histogram equalization (AHE) is a method for the local contrast enhancement. AHE computes several histograms of intensity values, each corresponding to a distinct region of the image, and uses them to redistribute the intensity values. AHE is very computationally...
We present a novel algorithm for reconstructing interferograms acquired in optical frequency domain imaging (OFDI). The algorithm was developed specifically for processing in field programmable gate arrays (FPGAs) and featured the use of a finite-impulse-response (FIR) filter implementation of B-spline interpolation for efficiently re-sampling k-space. When implemented in FPGAs, the algorithm allowed...
