tumourkit.preprocessing.pngcsv2centroids.extract_centroids(img: ndarray, csv: DataFrame) → List[Tuple[int, int, int]]

Extracts the centroids of cells from a labeled image. The third coordinate is the class.

Parameters:

• img (np.ndarray) – A 2D NumPy array representing the labeled image. Each unique non-zero value represents a different cell.

• csv (pd.DataFrame) – A pandas DataFrame representing the labels. Just two colums, one for id and another for the class.

Returns:

A list of tuples containing the x and y coordinates of the centroid, and the cell class.

Return type:
