The algorithm used inSuperpixels3
一世s一个modified version of the Simple Linear Iterative Clustering (SLIC) algorithm used by超级像素
。在高水平上,它创建集群中心,然后在将像素分配给最近的集群中心和更新群集中心的位置之间进行迭代交替。Superpixels3
使用距离度量标准确定每个像素的最接近的群集中心。该距离度量结合了强度距离和空间距离。
The function'sCompactness
参数来自d的数学形式一世st一个nce metric. The compactness parameter of the algorithm is a scalar value that controls the shape of the superpixels. The distance between two pixels一世一个ndj, 在哪里m是紧凑的值是:
Compactness has the same meaning as in the 2-D超级像素
function: It determines the relative importance of the intensity distance and the spatial distance in the overall distance metric. A lower value makes the superpixels adhere to boundaries better, making them irregularly shaped. A higher value makes the superpixels more regularly shaped. The allowable range for compactness is((0 Inf)
,,,,一个s一世nthe 2-D function. The typical range has been found through experimentation to be[[0.01 0.1]
。输入图像的动态范围在算法中归一化为0至1。这可以使整个图像的紧凑值的含义一致。
