Performance of the algorithm in the presence of noise.

Percentage of true positives, false negatives, and false positives with increasing variance of multiplicative noise (σ2) applied to a volume before the automatic processing through See Elegans. The increasing level of noise increases the number of false negatives and decreases the number of true positives, thus affecting the accuracy.在经See Elegans进行自动处理前，对三维图像体积施加乘性噪声（multiplicative noise），随该噪声方差（σ²）递增时的真阳性（true positives）、假阴性（false negatives）与假阳性（false positives）占比情况。噪声水平的提升会增加假阴性的数量并降低真阳性的数量，进而对分析准确率造成影响。
