_hausdorff_metric

_hausdorff_metric(
    set1::Vector{CartesianIndex{N}}, set2::Vector{CartesianIndex{N}};
    per::Union{Nothing, Real}=nothing, directed::Bool=false
) where N

Compute the Hausdorff distance between two sets of points, set1 and set2.

This function has multiple methods depending on the arguments provided:

1. Without per: Computes the standard Hausdorff distance.
2. With per: Computes the Hausdorff distance at the specified percentile.

Arguments

• set1: First set of points in 2D or 3D space.
• set2: Second set of points in 2D or 3D space.
• per: Percentile for the Hausdorff distance (optional).
• directed: If true, computes one-sided Hausdorff. Default is false.

Returns

• Hausdorff distance or Hausdorff distance at the specified percentile.

compute_min_euc_distances

compute_min_euc_distances(set1::Vector{CartesianIndex{N}}, set2::Vector{CartesianIndex{N}}) where N

Compute the minimum Euclidean distances for each point in set1 to every point in set2.

Arguments

• set1: First set of points in 2D or 3D space.
• set2: Second set of points in 2D or 3D space.

Returns

• Vector of minimum Euclidean distances.

dice_metric

dice_metric(prediction::AbstractArray, ground_truth::AbstractArray)

Compute the Dice Coefficient (also known as the Sørensen–Dice index) between two binary masks, prediction and ground_truth.

The Dice Coefficient measures the similarity between two sets and ranges from 0 (no overlap) to 1 (perfect overlap).

Arguments

• predicted_segment: Predicted binary mask.
• ground_truth_segment: Ground truth binary mask.

Returns

• Dice Coefficient value between the two masks.

hausdorff_metric

hausdorff_metric(
    prediction::AbstractArray, ground_truth::AbstractArray;
    per::Union{Nothing, Real}=nothing, directed::Bool=false
)

Compute the Hausdorff distance between two masks, prediction and ground_truth.

This function has multiple methods depending on the arguments provided:

1. Without per: Computes the standard Hausdorff distance.
2. With per: Computes the Hausdorff distance at the specified percentile.

Arguments

• prediction: Predicted mask, 2D or 3D array of ::Bool or ::Int.
• ground_truth: Ground truth mask, 2D or 3D array of ::Bool or ::Int.
• per: Percentile for the Hausdorff distance (optional).
• directed: If true, computes one-sided Hausdorff. Default is false.

Returns

• Hausdorff distance or Hausdorff distance at the specified percentile.
