Module array4d 

4D spatiotemporal array support for scirs2-ndimage.

Provides Array4D<T> with shape [T×D×H×W] and operations including Gaussian filtering, temporal differencing, MIP, connected components 4D, and region tracking.

Structs

Array4D

A 4-dimensional array with layout [time, depth, height, width].

TrackletResult

Result of tracking a labeled region across time frames.

Functions

connected_components_4d

Compute connected components of a binary 4D array via BFS.

diff_4d_temporal

Compute temporal finite differences: output[t] = input[t+1] - input[t]. Output shape is [T-1, D, H, W].

gaussian_filter_4d

Apply separable Gaussian filtering to a 4D array.

max_intensity_projection_4d

Maximum intensity projection along the specified axis.

track_regions_4d

Track labeled regions across time frames by majority overlap.

Type Aliases

Label4D

Label array for 4D connected components (0 = background, ≥1 = labels).
