From: FPGA-embedded Linearized Bregman Iteration algorithm for trend break detection
Results of trend break detection on a testbench real-world fiber profile acquired in laboratory conditions. Red and blue traces correspond, respectively, to the results from the 64-bit floating point and 20-bit SFIXED bit-true versions of the LBI algorithm. The traces are vertically offset in order to highlight the correct trend break detection, but the original baseline is the same. The inset displays a zoomed-in segment of the profile, where faults close to one another have been correctly identified by both versions of the algorithm
