High Dynamic Range image tone mapping based on local Histogram Equalization
High Dynamic Range (HDR) images can represent the acquired scene with a greater dynamic range of luminance than classical Low Dynamic Range (LDR) ones. Despite the recent diffusio...

Beyond the arithmetic constraint: depth-optimal mapping of logic chains in LUT-based FPGAs
Look-up table based FPGAs have migrated from a niche technology for design prototyping to a valuable end-product component and, in some cases, a replacement for general purpose pr...
