k均值 # STEPS: # 0 - Choose k random centroid coordinates # For each pixel x: # 1 - Calculate rgb distance of x from each centroid # 2 - Assign x to closest centroid's cluster # For each centroid c: # 3 - Calculate rgb means of assigned pixels for that c (move the centroid) # repeat until all x are stable, 输出 标签：4 mean_diff_threshold：5.0
