Detection Settings

sb_region_ratio Higher: searches only lower part for scale bar. Lower: searches a wider vertical area. white_thr For white scale bars. Higher: stricter bright-pixel selection. black_thr For black scale bars. Higher: includes more dark-gray pixels. sb_min_area Higher: removes small scale-bar candidates and noise blobs. crop_bottom_px Higher: removes more bottom area from dot analysis ROI. gamma Higher: darker image; Lower (<1): brighter image before thresholding. gauss_sigma Higher: stronger blur, less noise but softer edges. adapthist_clip Higher: stronger local contrast, but may amplify noise. adapthist_tile_y Higher: finer vertical local contrast regions. adapthist_tile_x Higher: finer horizontal local contrast regions.
