Image segmentation中,模型分割出的mask就是影像的挑选总数,专家标记的mask就是正确总数。对应到公式便可知挑选总数(TP+FP)和正确总数(TP+FN)分別就是X和Y,交集便是TP,可見Dice coefficient等同F1 score,直观上是计算X与Y的相似性,本质上则同时隐含Precision和Recall两个指标。
前言:What is a good image decomposition?[1] (i) the recovered layers, when recombined, should yield the input image. (ii) Each of the layers should be as “simple” as possible, namely, it should have a stronginternalself-similarityof “image elements”. (iii) The recovered layers should...
6. Image segmentation is the division of a digital image, called superpixels, into smaller parts to facilitate ease of analyzation or meaningfulness. Several methods exist to segment an image, including thresholding, clustering, compression-based, histogram-based, edge detection, region-growing, split...
