Parameter

Description

Implication

points_per_side

Number of sampling points along each side of the image grid.

Higher values improve granularity but increase computation.

pred_iou_thresh

Minimum IoU threshold for mask predictions.

Stricter thresholds (e.g., 0.7–0.9) enhance precision but may exclude valid masks.

stability_score_thresh

Filters masks based on their stability across scales.

Higher values (e.g., 0.9–0.95) favor stable masks but risk discarding borderline regions.

crop_n_layers

Number of hierarchical cropping layers for segmentation.

More layers improve segmentation of small objects but increase processing time.

crop_n_points_downscale_factor

Downscales the number of points sampled in cropped regions.

Smaller factors preserve resolution but increase computational cost.

min_mask_region_area

Minimum size of mask regions

Filters small noisy masks. Set this based on object size in your dataset (e.g., around 0.1–1% of image resolution).
