Fig. 6From: Application of image-recognition techniques to automated micronucleus detection in the in vitro micronucleus assayMicronucleus detection results corrected in individual mode. The threshold for micronucleus detection is at the values of (A) 0.5, (B) 0.6, (C) 0.65, and (D) 0.7. Small letters and prime letters indicated the enlarged view of each position. (A, B) The inappropriate threshold. White arrows pointed to a white-lined circle where the MN was not presented (White arrows were displayed by the author). (C) The optimum value of the threshold. (D) Inappropriate threshold. Even the detected MN was lostBack to article page
