Black-Hat Transform | 555Tools — Online Tools for FPGA & Algorithm Engineers

Image AlgorithmsTool Introduction

Black-Hat = closing(src) - src. Closing fills small dark spots; subtracting original from closing result extracts those dark details. FPGA uses closing module cascade with input delay chain for alignment.

Key Formula / Principle

BlackHat(I) = Closing(I) - I
Delay chain = 2x(2*IMG_W + 2) cycles
Dark detail extraction: isolates small dark spots and holes
